Haier Air Conditioner Troubleshooting [Step By Step Guide]

Haier air conditioners are designed to last as long as possible, even when it is used for hours a day. However, there can still be instances of problems arising over time. If you run into problems with your Haier air conditioner, follow the troubleshooting steps below.

The problem may be due to the installation, climate, or other factors. But this should help you get the unit up and running.

Whenever you are looking for an AC, Haier is the first name that comes to your mind. With the Haier Air Conditioner Troubleshooting, you can easily get to know about all the issues related to the air conditioners and their solutions, with ease.

Haier Air Conditioner Troubleshooting Guide

Air conditioners are pretty simple. Most of the time when something goes wrong with your unit, it’s something pretty minor and easy to fix yourself. You can troubleshoot first, though, and take a look at your unit to see if you can identify the problem.

Also, most air conditioners have self-diagnostic features that will lead you in the right direction.

Haier Air Conditioner Not Blowing Cold Air

When the air conditioner is not blowing cold air, the common reason is that there is a clog in the system. In that way, it does not circulate the air as it should be. And, as a result, the air conditioner will not work as it should be.

In other cases, the problem might be with the compressor. The compressor is not pumping the refrigerant as it should be. It is the part of the air conditioner that is responsible for the cooling.

Leaking or Low Refrigerant

When your air conditioner’s refrigerant level is low, there is insufficient pressure. This causes the air conditioner to blow air that is warm or tepid.

Check the refrigerant level and ensure that there are no leaks. Some air conditioners use fair amount of refrigerant, thus leading to a quick depletion of the entire contents.

If you suspect that the air conditioner is not cooling properly due to low refrigerant, you should contact the store where you purchased the unit or a trained repairman and ask that they check your unit’s refrigerant level.

Dirty Or Clogged Filter

If the filter is dirty or clogged, chances are it will reduce how much air can flow through it, causing the unit to not cool effectively. It’s important to inspect and clean the filter monthly, especially during the peak cooling season.

Check the air conditioner’s owner’s manual and follow the instructions.

Evaporator Coil or Condenser Problem

f the evaporator coil or condenser coil is dirty or has been covered with frost, the air conditioner will be unable to cool the home properly. Cleaning the evaporator and condenser coils can go a long way in improving the cooling efficiency of a home air conditioner.

In addition, the evaporator and condenser coils are covered with fins. The fins can get bent during routine use over the test of time. This can also make the evaporator and condenser coils unable to absorb and release enough heat, respectively. Adjusting the fins with a fin comb can also improve the cooling efficiency of the unit.

If the evaporator coil is frozen over for any reason, the air conditioner will not work properly. The evaporator coil is the part of the air conditioner where the refrigerant is converted into cool air. If there is a problem with the evaporator coil (or if it is frozen over), then the air conditioner will not be able to produce cold air.

Blocked or Clogged Registers

A blocked or clogged register is a very common cause of an AC not blowing cold air. Perhaps you’ve even noticed one before. The solution to compressed air being unable to flow properly through a blocked or clogged register is to clean the register.

In the short term, this can be done by simply taking a vacuum cleaner with a brush attachment and gently brushing the lint and dust buildup off of your register. In the long term, this will mean having a professional come in and clean your vents for you.

If your air conditioner is not blowing cold air, it might be due to dirty or blocked registers. A blocked register can also cause your air conditioner to freeze. To clean or unblock air registers, follow these steps.

The first step is to identify the source of the blockage. The most likely culprits are rugs, carpets and furniture. If you have any of these in front of your air registers, simply move them out of the way.

Check for any insects or debris that might be blocking the airflow. Use a vacuum cleaner to remove any dirt or debris.

Inspect the registers themselves for any blockages. If you see any, use a brush or vacuum cleaner to remove them.

Once you’ve cleared the blockages, turn on your air conditioner and check to see if cold air is blowing out of the registers.

Thermostat Issue

This is a common problem, but also one that is easy to fix. The problem is usually with the thermostat. Sometimes, it’s because the thermostat is set to “on” or “heat” instead of “auto”.

Other times, it’s because the thermostat is not set to the correct temperature. The thermostat should be set to the temperature that you want the room to be, not the temperature that it currently is.

If the thermostat is set to the correct temperature but the air conditioner is still not blowing cold air, then the problem is likely with the air conditioner itself.

Haier Air Conditioner Compressor Not Running

The compressor is the heart of the AC. If it is not running, the whole system can break down. It will not run when the pressure of the Freon is too low. When this happens, the compressor can overheat, which will lead to the compressor not running.

It will also not run if the compressor is getting overheated, so the AC will not cool the house.

Dirty Coil And Filters

If your Haier air conditioner compressor is not running, then the first thing you need to check is the coils and filters. The coils and filters may be dirty, causing the compressor to overheat and shut down.

Clean the coils and filters with a vacuum cleaner or brush.

Capacitor And Starter Relay Problems

If your Haier air conditioner is not working right and the compressor isn’t running, the problem might be a faulty capacitor, starter relay, or both. Here is how to test and replace these parts in an air conditioner:

1. Turn off the power to the air conditioner.
2. Test the capacitor with a multimeter to see if it is working. A bad capacitor will usually show a reading of infinity on the multimeter.
3. Test the starter relay by removing it from the air conditioner and testing it with a multimeter. A bad starter relay will usually show a reading of infinity on the multimeter.
4. If either the capacitor or starter relay is bad, replace it with a new one.
5.  Turn on the power to the air conditioner and test it to see if it works.

Dead Compressor

Compressor failure is one of the main reasons an air conditioner will not turn on. The compressor is the central component of your AC unit, which is responsible for circulating the refrigerant throughout your system.

If the compressor is damaged or has failed, your AC unit will not be able to circulate refrigerant and will not turn on.

Power

One of the most common reasons for a Haier air conditioner compressor not to run is a lack of power supply. There could be a problem with the power source or the power cord. Another possibility is that a circuit breaker has tripped.

If the problem is with the power cord, you should check it for any frayed wires or other damage. If the problem is with the power source, you should check the circuit breaker and reset it if necessary.

Haier Air Conditioner Not Heating

If the Haier air conditioner isn’t heating then you may have one of the following problems:

1. Check the circuit breaker. If the Haier air conditioner isn’t working then the first thing to check is the circuit breaker. There may be a tripped circuit breaker. You can reset the circuit breaker and see if it works. If not, then you may have to replace the breaker.

2. Check the air filter. A dirty air filter can prevent the Haier air conditioner from heating properly. You should clean or replace the air filter once a month.

3. Check the thermostat. The thermostat controls the temperature of the air conditioner. If it’s set too low, then the air conditioner won’t heat properly. You should set the thermostat to at least 75 degrees Fahrenheit.

4. Check the evaporator coils. If these coils are dirty, then this may prevent your air conditioner from working properly. You should clean the coils or replace them.

5. Check the blower assembly. This assembly pushes cold air into your rooms. If it isn’t working properly, then this will prevent your Haier air conditioner from heating up your rooms. To fix it, you need to replace the blower assembly.

Haier Air Conditioner Won’t Turn ON

Is your Haier air conditioner not turning on? This can be due to a number of issues. Here are the most common reasons your Haier air conditioner won’t turn on:

There are several reasons why a Haier air conditioner might not turn on. The most common reason is that the air conditioner is not getting enough power.

Check to make sure that the air conditioner is plugged into an outlet that is providing enough power. If the air conditioner is plugged into a surge protector, make sure that the surge protector is turned on. Another common reason for an air conditioner not turning on is that the air conditioner is not set to the correct setting.

Make sure that the air conditioner is set to the correct setting for the room you are trying to cool.

Tripped Circuit Breaker

If your Haier air conditioner won’t turn on due to a tripped circuit breaker, simply flip the breaker switch back to the “on” position.

Blown Fuse

If your Haier air conditioner is not turning on, it may be due to a blown fuse. The first thing you should do is unplug the unit and check the fuse box for a blown fuse.

If you find a blown fuse, replace it with a new fuse and plug the unit back in. If the unit still does not turn on, it may be due to a faulty air conditioner capacitor.

Clogged Air Filter

The most common cause of an air conditioner not turning on is a clogged filter. The filter is designed to remove impurities from the air, but if it becomes clogged, it can restrict the flow of air and prevent the unit from turning on.

To clean the filter, first turn off the power to the unit. Then, remove the filter and rinse it with warm water. Allow the filter to dry completely before reinstalling it. If the filter is heavily damaged, it may need to be replaced.

Dirty Evaporator Coils

If your Haier air conditioner won’t turn on, the first thing you should check is the evaporator coils. If the evaporator coils are dirty, the air conditioner won’t be able to cool the air properly. Clean the evaporator coils with a vacuum cleaner and make sure they are dry before turning the air conditioner on again.

Dirty Condenser Lines

In the case that the Haier air conditioner won’t turn on, the first thing to check is the condenser lines. If the condenser lines are dirty, it will prevent the unit from turning on.

To clean the condenser lines, disconnect the power to the unit and remove the front panel. Next, use a brush to clean the condenser coils. Finally, reconnect the power and turn on the unit.

Refrigerant Leak

If your Haier air conditioner is not turning on, it might be due to a leak in the refrigerant. The refrigerant is a substance that helps cool the air in the air conditioner. If there is a leak, the air conditioner will not be able to cool the air properly.

You will need to have the leak fixed by a professional before the air conditioner will work again.

Check Thermostat

The first thing to check is whether the batteries in the thermostat are working. If not, then replace the batteries. If the batteries are working, then check to see if the thermostat is set to the correct temperature.

If not, then adjust the thermostat to the correct temperature. Finally, check to see if the air conditioner is turned on. If not, then turn on the air conditioner.

Haier Air Conditioner Keeps Turning Off

There could be a few reasons why your Haier air conditioner keeps turning off. The most common reason is that the air conditioner is set to the “auto” setting, which turns the unit off when the room reaches the desired temperature.

Other reasons could include a power outage, a tripped circuit breaker, or a blown fuse. If the problem persists, you may need to contact a certified Haier service technician for further assistance.

Air Filter

The air conditioner has an air filter that needs to be changed regularly. The air filter is designed to clean the air coming into your home.

If the air filter is not changed regularly, it will get clogged and the air conditioner will have to work harder to push the air through the filter. This will cause the air conditioner to turn off.

Thermostat

The air conditioner has a thermostat that controls the temperature of the air inside your home. If the thermostat is set too high, the air conditioner will turn off. It is important to make sure that the thermostat is set to the correct temperature so that the air conditioner does not turn off.

Dirty Coils

The air conditioner has coils that need to be kept clean. The coils help transfer the heat from inside the home to the outside. If the coils are dirty, they are not going to be able to transfer the heat.

A dirty coil can cause the air conditioner to overheat and turn itself off. Clean or replace the air filter regularly. Adjust the temperature on the thermostat so that it is neither too high or too low. Replace dirty or damaged coils.

Check Circuit Breaker

Make sure that the unit is plugged into a working outlet and that the circuit breaker has not been tripped.

If your air conditioner isn’t receiving enough power, it will shut off automatically to prevent damage. Make sure the air conditioner is plugged into a working outlet and that the circuit breaker hasn’t tripped.

Refrigerant leak

If your Haier air conditioner keeps turning off due to a refrigerant leak, the first thing you’ll want to do is check the unit’s Freon levels. If the Freon levels are low, you’ll need to add more Freon to the unit. If the Freon levels are fine, then the problem may be with the unit’s compressor.

Haier Air Conditioner Leaking Water

Generally, air conditioners are built to extract water from the air and release it out the back of the unit. However, this is not always the case. Oftentimes, the products we purchase do not work as we expect them to.

The most common reason why Haier air conditioners leak water is because of a blocked drainage pipe. The pipe that is responsible for carrying water away from the air conditioner can become blocked with debris, dirt, or even leaves. When this happens, the water has nowhere to go and will instead seep out of the unit, causing it to leak.

Another reason why your Haier air conditioner may be leaking water is because the unit is not level. If the unit is not level, the water will not be able to drain properly and will instead spill out.

The third reason why your Haier air conditioner may be leaking water is that the drains are full. The drains of an air conditioner are designed to dump excess water outside of the unit. If they are full, they cannot perform this function and will instead spill out onto the floor. To prevent this from happening, you should ensure that the drains have room to work.

Haier Air Conditioner Control Panel Not Working

A Haier air conditioner’s control panel not working can be caused by various factors. The most common reason is that the power cord is not plugged into the outlet. Another possibility is that the circuit breaker has been tripped.

If neither of these is the problem, then it is likely that the control panel itself is defective.

There are a few reasons why your Haier air conditioner’s control panel might not be working. Here are some of the most common reasons:

1. The air conditioner is not receiving power. Check to make sure that the air conditioner is plugged into a working outlet. If it is, then check to see if the circuit breaker has tripped. 
2. The air conditioner’s control panel is not properly connected. Make sure that the control panel is firmly attached to the air conditioner.
3. The air conditioner’s control panel is defective. If the air conditioner’s control panel is not working, then it will need to be replaced.

Haier Air Conditioner Not Cooling

There are a few reasons why the Haier air conditioner might not be cooling. It could be that the air conditioner is not getting enough power, the air conditioner is not properly charged, or the air conditioner is not properly ventilated.

There are a few reasons why your Haier air conditioner might not be cooling as efficiently as it once did. Here are some of the most common reasons:

The air filter is dirty

If the air filter is clogged with dirt and debris, it will restrict the airflow and prevent the air conditioner from cooling properly. To clean the air filter, simply remove it from the unit and rinse it with warm water.

The coils are dirty

The coils inside the air conditioner can also become clogged with dirt and debris, which will restrict airflow and prevent the unit from cooling properly. To clean the coils, simply remove them from the unit and rinse them with warm water.

The refrigerant is low

If the air conditioner is low on refrigerant, it will not be able to cool the air properly. If you notice that the air conditioner isn’t cooling the air as well as it used to, the refrigerant might be low. To check, simply remove the front grill and check the gauge. If it is below the “Full” mark, you will need to add more refrigerant.

The condenser is dirty

If the condenser gets dirty and clogged with debris, it will not be able to perform its job properly.

The thermostat is set too high

If the thermostat is set to a higher temperature, the air conditioner will work harder and use more energy but it will not be able to cool the air down to the desired temperature. You can set the thermostat a few degrees lower to increase your energy efficiency.

The blower is clogged with dust and debris

If the blower is clogged with dust, it will not be able to circulate air throughout the room. To check if the blower is clogged, plug in the unit and turn it on.
