Amana Air Conditioner Troubleshooting [Step By Step Guide]

If you’re having any problems with your Amana Air Conditioner, there are a few things you can do before calling a professional. Overheating, freezing and a lack of cooling can all be caused by problems with your unit or by issues with the ductwork. The following are some common problems and solutions.

The Amana brand has been around for over a century, and they’re world renowned for their air conditioning units. While you can’t go wrong with an Amana air conditioner, there’s a chance you might have to deal with a problem sooner or later. If so, you’ll want to give our guide a read.

Today we will be taking a look at how to troubleshoot your Amana Air Conditioner should you notice any problems.

Amana Air Conditioner Troubleshooting Guide

If your Amana air conditioner isn’t working properly, you may be able to troubleshoot the problem yourself. This troubleshooting guide can help you identify the problem and find a solution.

When a cooling device isn’t acting up, you may be tempted to call for customer service. However, this is not always necessary. First, look at the manual; if possible, determine what went wrong and how to fix it yourself. If you can’t figure out how to do so, contact customer support.

A well-maintained air conditioner works in both summer and winter for years. Basic maintenance as well as quick repairs can help your system run efficiently and effectively for years. If you’re curious about how well your AC is performing, try monitoring its energy use over time with a A Watt or similar device.

If your unit’s running consistently at maximum capacity, it may be time to have the unit inspected or repaired — a professional technician can determine the cause of technical issues by testing the components themselves.

Amana AC Not Blowing Cold Air

If your Amana air conditioner is not blowing cold air, there are a few things that you need to check.

Check Power Connections

First, make sure the Amana AC unit is turned on. Check for power to the unit by removing the cover over the control board. Use your multimeter to check for voltage from the 24 volt transformer.

If no voltage is found, check for a loose or burned wire connector or a blown fuse inside the Amana AC unit. If voltage is found but the unit will not come on, start checking for bad connections and blown fuses.

Finally, if the unit will start but shuts down after a few minutes, check the low voltage cut-off relay. It could be defective.

Incorrect Thermostat Setting

An uncooperative air conditioning system often points to a problem with your thermostat, which may be set at an incorrect temperature. If your thermostat is on Auto instead of ON, it might not turn on if it thinks the temperature in the room isn’t cool enough.

And if the thermostat’s threshold is set higher than the actual outside temperature , it might not correct itself. If the air conditioner is set too high, it may not switch on fully. For example, an 18°C temperature difference turns the air conditioning on at 24°C.

An AC unit needs to be able to properly cool down a room before it brings a noticeable change in temperature. This means that even if you notice your AC is blowing, it may still take some time for the inside of your home to cool down — up to a full hour in extreme heat.

For best results, try to manually lower the inside temperature by at least 2 degrees using your thermostat before you attempt to take any further action on the problem.

However, trying resetting the thermostat and seeing if this changes anything as well. If that doesn’t work, then it’s probably time to contact professional HVAC workers from an air conditioning repair near me instead.

Leaking or Low Refrigerant

Refrigerants are necessary for air conditioning and heating systems, making it an indispensable part of our households. The main refrigerant is Puron or R410A, which can be replaced by its cheaper counterpart HFO-1234yf that’s currently in use with minimal modifications to equipment.

Most leaks can be fixed at home by following the instructions provided in your AC unit. If you see excessive humidity and temperature changes within your house, there might be a refrigerant leak in your AC unit.

In this case, make sure to consult an HVAC professional right away.

Clogged Filter

When your AC filter is clogged, it can cause a number of problems. A dirty filter prevents proper air flow and forces your unit to work harder than it should — which can cut the life cycle of important parts shorter than they should be.

If you’ve noticed that your AC is struggling to keep up (and consequently, turning on and off frequently) or if you’re experiencing unusually high electric bills, it may not be a problem with the machine itself. It may be as simple as replacing its filter more often.

If you have pets, it’s a good idea to change AC filters regularly. Unless you’re an expert, though, changing the filter on your air conditioner is probably best left to the professionals — letting them handle any problems that might occur from clumsy interventions.

Problem With the Evaporator Coil or Condenser

Mold and mildew are both common problems that can be easily avoided through preventative maintenance. Neglecting to have your A/C system cleaned and inspected regularly could result in a more serious problem arising, like clogged coils, which may put strain on your entire system.

AC evaporator coils are susceptible to problems with mildew and mold.

Coil cleaning should be undertaken at least every year, as recommended by most air conditioner manufacturers. By using an air scrubber or by purchasing an ultraviolet light system to filter out contaminants in the air before they reach your HVAC system, you can guard against mold and mildew buildup on the coils.

Over time, your AC condenser can become worn out. If you notice that your air conditioner isn’t blowing cold air, and there doesn’t seem to be any other explanation, have the condenser checked.

Thermostat Issue

The thermostat is the central part of your air conditioning unit. When it senses that the room it’s in is colder than the setpoint on the thermostat, it starts to run and brings down the temperature until it reaches the set point.

One of the first steps in figuring out if your thermostat is working correctly is to check whether its mode has been changed. Check whether it is set to cool instead of auto.

If your AC unit is not turned on and it’s the right time of year, then the problem may be due to a faulty thermostat. The batteries for it may need to be replaced or the electronics could be broken — in this case you should hire an HVAC professional.

Amana AC Compressor Not Running

There are a few things that can cause this issue. The most common is that the capacitor has gone bad. This is a small, round, black component that is located near the compressor.

It provides power to the compressor, and if it has gone bad, the compressor will not start. Another possibility is that the compressor itself has gone bad. This is a more serious issue, and will require a replacement compressor.

Dirty Coil And Filters

If your air conditioner coil or air filter is dirty, the air conditioner compressor will not run. The air conditioner compressor is the pump that circulates the refrigerants through the air conditioner.

The compressor will not run if the air conditioner is not circulating refrigerant.

The air conditioner coil is located inside the air conditioner.

The coil is made of copper tubing and is filled with refrigerant. The coil is located in the air conditioner’s evaporator. The evaporator is located in the air conditioner’s indoor unit.

The air conditioner filter is located in the air conditioner’s outdoor unit. The filter traps dust, dirt, and other airborne particles. If the filter is dirty, the air conditioner will not be able to circulate air properly.

If the coil and filters are dirty it makes the system work harder and can cause the compressor not to run. It is best to have the system serviced once a year so that it can run at peak efficiency.

Capacitor And Starter Relay Problems

Modern air conditioners are often more complicated than they seem. When outside temperatures soar and the AC refuses to turn on, oftentimes one of three things is wrong — the thermostat, the capacitor, or the starter relay.

The thermostat turns on the ac compressor after you set a temperature threshold, but it isn’t complex enough to distinguish between turning off/on when you need to cool down versus when your home simply needs circulation.

The capacitor act as a temporary power bank that’s responsible for running the compressor and fan motors during start-up.

A bad capacitor may lead to an overload on other parts of your HVAC system.

Finally, when your air conditioner makes humming noises but remains unresponsive, then there’s a good chance that your starter relay has fried itself and malfunctioned.

Faulty Compressor

If your air-conditioning unit isn’t turning on, it can be a sign that something is wrong with the motor or compressor. The compressor might have burned out and stopped working because of an overload, or it could have been damaged from a power surge or just from old age.

In this case you need to replace the compressor.

Power Issues

One common reason that an ac compressor won’t start is a burnt-out compressor start relay. If the power isn’t getting to this relay, the unit’s electrical system checks it, determines no current is getting through and sends a signal to turn on the fan. The fan then runs off of your home’s main power supply.

This means that when you’re dealing with an issue with your ac’s connection to the power grid, check first that the fuse or circuit breaker hasn’t been tripped.

Amana Air Conditioner Not Heating

For reverse cycle systems, the most common reason for heating not occurring is because of dirty filters. Clogged or dirty filters can stop reverse cycle air conditioners from heating properly by reducing the amount of hot air available to warm up the space.

There are several reasons why your reverse cycle split or ducted air conditioner may not be heating properly. These include:

Ice Build Up

During the wintertime, ice can build up inside an air conditioning unit when the system gets too cold. As the indoor unit warms the air, it becomes less likely for ice to build up. If there is still some freezing happening, check to make sure that your home’s ventilation isn’t blocked in any way — both outside of and inside of the AC unit itself.

When ice builds up on the coils of an air conditioning unit, the system can greatly decrease in efficiency. This is because the excess ice acts like an insulator and prevents the unit from efficiently removing moisture from the air.

The broken parts of your air conditioner need to be fixed or replaced immediately so that they do not pose a risk to your home or office.

Circuit Breaker and Fuse Problems

When the circuit breaker of the air conditioner has been pulled out or is defective, this can lead to poor heating performance. If the circuit breaker is tripped on or is being fixed in some sort of aircon repair, it may need to be switched back on after awhile.

This can work great for most people — but if the system is still down, it will affect everything else that comes with your HVAC installation, including your ability to get to a comfortable temperature without difficulty.

Incorrect Temperature Settings

If you know that the temperature setting of your cooling system is not at a comfortable level, there could be nothing simpler than adjusting it accordingly. For instance, if the temperature has been accidentally set to ‘cold’ instead of ‘cooling’, this will result in the air conditioner blowing out cool air instead of heating the room.

From here, simply adjust the temperature settings and reconstruct your environment with a few simple clicks of a button.

Defrost Cycle

During the defrost cycle, the indoor fan blows out cold air to ensure that ice does not build up on the outdoor compressor unit. If ice does start to form, it will damage your air conditioner and possibly even cause permanent damage to your home.

The best way to prevent this from happening is by ensuring that your unit is set up correctly during installation with a professional who has access to all the necessary tools and parts needed for complete installation.

Amana PTAC Not Blowing Cold Air

If your Amana PTAC isn’t cool, check the thermostat. Your Amana air conditioner is most likely running too hot if your home feels uncomfortably warm — and the thermostat may be to blame.

If your Amana PTAC unit is not blowing cold air as expected, check the thermostat settings. Ensure that the temperature is set to your desired level and that the mode is set to “cool” and “auto.”

If your unit is operational, but the temperature of its controlled room isn’t warm enough, you may have a problem with the thermostat. There are many reasons that this could happen, but some common causes include the air filter being clogged or the limit setup being disabled.

Amana PTAC air filter has a tendency to get clogged after repeated use. But it is straightforward and simple to keep your air conditioners running smoothly in your commercial space or home.

First, check your filter on a regular basis. Are there any obstructions? Is the air flow impeded by anything that may have accidentally fell in front of the filter? Second, you should clean your filter regularly.

Your Amana PTAC unit has an air filter that needs to be checked and cleaned regularly. The filter is located in the curtain cover (indoor) portion of the PTAC. To clean the filter, simply rinse it in the sink or vacuum it with a hose attachment.

First, ensure that the PTAC unit is turned off and unplugged from the power source. Next, remove the cover of the unit. You may need to use a screwdriver to loosen any screws that are holding it in place.

Next, clean the vent screen.

If your air conditioner isn’t working properly, one possible issue is dirty or kinked evaporator coils. To clean the coils, first straighten any kinks with a coil fin comb. Then apply HVAC coil cleaner and scrub until the coils are clean. Replace the cover and try again to see if the unit just needed cleaning.

If you notice your PTAC making strange noises, it could be a sign that the compressor is having issues. In this case, it’s best to call in a professional rather than attempt a repair on your own.

Amana Air Conditioner Won’t Turn ON

If your Amana unit isn’t turning on, the problem could be a lack of electricity to the unit or the components that are used to turn the unit on. You may have a tripped breaker or a blown fuse.

Check Circuit Breaker

The first thing that you should do is check your breaker. Your air conditioner will have one breaker in your home’s breaker box, which supplies power to all of the air conditioner’s components.

If this breaker has tripped, you’ll need to simply reset it by flipping the switch to the ON position. If the breaker trips again, you’ll need to check all of the connections to the breaker to ensure they’re tight and secure.

Also, make sure the wires are in good condition with no fraying or bare spots. If you see any damage to the wires, you’ll need to call an electrician immediately to repair the damage and reroute the wires.

Thermostat Issues

If your thermostat isn’t working properly, then your air conditioner won’t know when to turn on. This can be a big problem if you rely on your AC to keep your home comfortable.

If your thermostat doesn’t respond as it should, check to see if the batteries are dead. If they are, replace them with new ones. A missing image or blank display could mean the thermostat is broken and needs professional repair.

Condenser Unit Unplugged

If your air conditioner is not turning on, start by checking if the cord coming out of it has been damaged (by looking at the wires and plug, using a flashlight to illuminate the area).

This can be caused by loose outlets or chewed-through wires. To check this, unplug your AC and look at both ends of the wire — do they seem fine? Is there any damage to the plug that connects the wire to your wall? Are the wires securely in place on both ends?

If your air conditioner isn’t working, the problem could be as simple as it not being plugged in. Check the cord coming out of your AC unit.

In most cases, there will be a small brown cord connected to the panel. If your home’s AC unit isn’t working, it could be because the wires are unplugged or damaged. Without electricity, the AC can’t switch on.

Blown Fuse

First, check the fuse in your fuse box to see if it has blown. If it has blown, it will need to be replaced. If the fuse has not blown, unplug the unit and plug it back in. If this does not work, the unit may need to be reset.

To reset the unit, turn the power switch to the “OFF” position and then back to the “ON” position.

Clogged Air Filter

A clogged air filter will prevent the AC from turning on because it will not allow air to flow through the system.

The air filter is located in the return air duct and is responsible for filtering out dust and dirt from the air before it enters the AC unit. If the air filter is clogged, it will need to be cleaned or replaced.

AC Motor Failure

An  AC capacitor  is the component that charges your air conditioner. A faulty capacitor may be responsible for the failure of a unit to turn on.

In order to test this component, you must first turn off the AC and cut its power supply before testing its motor with a multimeter. If the motor is not broken, then it may be the capacitor leading to your air conditioner’s malfunction.

Amana Air Conditioner Keeps Turning Off

There are a number of reasons why your Amana air conditioner might keep turning off and on. One possibility is that the unit is not getting enough air flow. This can be caused by a dirty filter or by a blockage in the ductwork.

Another possibility is that the unit is overworked and needs to be turned off for a period of time to cool down.

Evaporator Coil Issues

The coils of the air conditioner’s evaporator are responsible for removing heat from indoor air. When these coils become dirty, condensation can form and freeze on them. This causes the AC system to have to work harder to thaw the coils, but it will quickly shut off due to overheating.

If your evaporator coils are clogged, they won’t be able to absorb heat as well. This can cause your AC unit to freeze up.

You’ll need to clean the coils to remove the debris and restore proper heat transfer. If your evaporator coils are frozen, you’ll need to thaw them out before you can clean them. You can do this by turning off your AC unit and turning on the fan.

Once the coils are thawed, you can clean them with a brush or vacuum. Be sure to remove all debris so that the coils can function properly.

Refrigerant Problem

A refrigerant leak also causes short cycling. If a frozen evaporator coil is the result of a refrigerant leak, strange hissing noises will be heard as well as abnormally humid indoor air.

Low refrigerant due to a problem with metering or a hole in the refrigerant line may disrupt the cooling system, prompting short cycling.

Poorly-Sized Air Conditioner

Air conditioning is measured by output. In order to find the right unit for your room, make sure that you measure the square footage of the space and consider the humidity levels in the area. It is important that you have a ratio of one ton per 450 sq ft. You may go up or down a bit, but too much will lead to under- or over-cooling of your home or office.

Dirty Air Filter

If you have a dirty air filter, your unit will not have the capacity to fully cool your home. While it’s still working hard to keep up with excessive demand for cooling, it could cause your compressor to work harder, which creates excess heat.

Unfortunately, this will lead to your AC component overheating and potentially breaking down — but you can avoid this scenario by replacing or cleaning your air filter monthly.

Faulty Run Capacitor

We all like to keep our homes cool and beautiful during the hot summer months. And of course, we don’t want to have to worry about our air conditioner failing at the worst possible time.

A run capacitor, which is connected in series with your home’s electrical current, helps your AC unit keep running and working when you need it most.

When a run capacitor malfunctions, your air conditioner will be given power at irregular intervals. This may cause your AC to shut off unexpectedly.

Amana Air Conditioner Leaking Water

If you are a homeowner with an air conditioner unit and you have experienced the unpleasant surprise of finding water dripping from your air conditioner, you might be wondering what causes this and how you can fix it. There are a few different reasons that your air conditioner could be dripping water and below are some tips to help you determine the cause of the problem and how you can fix it:

If you see water dripping from your air conditioner, the first thing you should check is the air filter. A clogged air filter can cause your air conditioner to drip water. You should always check your air filter monthly and replace it as needed.

Another potential reason for water dripping from your air conditioner is that the evaporator coils are freezing. When the evaporator coils freeze, they can cause water to drip from your air conditioner.

There is a third potential cause for water dripping from your air conditioner. Occasionally air conditioners can develop leaks. If the seal on your air conditioner is broken it can cause water to leak from inside the unit. You should call a professional for this issue.

Reset Amana Air Conditioner

To properly reset your Amana air conditioner, you must first turn the unit on. Then, tap and hold the reset key for approximately five seconds. After that, press and hold the reset key for an additional five seconds.

Finally, wait for the unit to complete the resetting process, during which a red light will flash or blink.

Amana Air Conditioner Control Panel Not Working

If your AC blower is working, but your AC unit isn’t cooling, check whether an air conditioner control panel not working is the culprit. To check the status of your control panel, look for the following situations:

Lights are off in the AC panel—If your air conditioner panel lights are blinking or completely off, your AC may not work. Check your circuit breaker to see if it has been tripped. Also, make sure that the power cord is plugged into the outlet.

Air conditioner panel is completely blank—If you can’t see any lights on the AC panel, it may mean that the panel itself isn’t working. If your AC panel is more than 10 years old, it may be time to replace it. Also, make sure that the fuse isn’t blown.

Amana Air Conditioner Not Cooling

If your air conditioner is not cooling your house, there are a few things that you can check to see if there is an issue.

Wrong Thermostat Settings

When you notice your home getting a little hotter than normal, checking the thermostat settings is always the first step. Be sure it is set to cool before moving on to other possible causes.

If the thermostat is set to cool and there doesn’t seem to be any change, check the temperature setting to make sure it wasn’t changed by accident. If it’s off, set to heat, or set for constant fan (sometimes simply labeled “on”), switch it back over to cooling operation.

After the system kicks on, wait a few minutes, then check for cold air blowing from the registers. All being well, this should have solved the problem!

Dirty Air Filter

The air filter is one of the first parts you should check if your AC is not cooling. A dirty or blocked air filter will make your AC work harder, using more energy and ultimately causing it to fail.

Debris and dust can reduce air flow, making your AC less efficient. It can also cause your AC to freeze up. A new air filter only costs a few dollars, so it’s worth checking this first. Replace the filter and see how your AC responds.

Evaporator Coil Is Frozen

The evaporator coil may be frozen if the air conditioner is not cooling properly. This can be caused by a variety of issues, such as a dirty air filter, a clogged evaporator coil, or a problem with the air conditioner’s refrigerant level.

If the evaporator coil is frozen, it will need to be thawed out before the air conditioner can be used again. To thaw the evaporator coil, turn off the air conditioner and set the thermostat to the highest setting.

Then, use a hair dryer or a space heater to thaw the ice on the coil. Once the ice is melted, the air conditioner can be turned back on.

Refrigerant Leak

If the air conditioner is not cooling, there may be a refrigerant leak. The most likely place for a refrigerant leak is at the condenser, which is the large, coils of metal that sits outside of the home.

The refrigerant may also leak at the evaporator, which is the coils of metal that sits inside of the home. If the refrigerant is leaking, it will need to be replaced.

Undersized Air Conditioner

Additionally, if your AC is undersized, it may not be as efficient, and this will cost you more money in the long run. HVAC technicians are familiar with sizing air conditioners, and you should contact one to determine the best unit for your home. 

If your AC unit can’t handle the load, it will operate continuously and be less efficient. Additionally, your AC will lose its cooling capacity over time, which will make your home feel less comfortable.
