Frigidaire Window Air Conditioner Troubleshooting Guide
The Frigidaire Window Air Conditioner Troubleshooting Guide can help you determine what is causing your AC unit to not function correctly.
It is important to first identify the issue that you are having before attempting to fix it.
Frigidaire Window Air Conditioner Not Blowing Cold Air
There are a few reasons why your Frigidaire window air conditioner may not be blowing cold air.
AC is Not Properly Sized For The Room
This is the most common reason why your Frigidaire window air conditioner is not blowing cold air. Your window air conditioner needs to be sized properly for the room in order to function properly.
If your window air conditioner is too small for the room, it will not be able to cool the room properly. If your window air conditioner is too big for the room, it will cool the room too quickly and will not remove all the humidity from the air.
Dirty Air Filter
The air filter inside the air conditioner collects dust and other particulates over time. If these are not cleaned regularly, they could be the reason your Frigidaire window air conditioner is not blowing cold air.
Clean the air filter and see if the problem is resolved.
The thermistor monitors the temperature inside the air conditioner. If it senses a temperature that is too high, it will shut off the air conditioner to prevent damage.
If your air conditioner is not blowing cold air, the thermistor may be defective. To test the thermistor, use a multimeter to test it for continuity. If the thermistor does not have continuity, replace it.
If the Frigidaire window air conditioner is not blowing cold air, it is most probably due to a leak in the refrigerant line. The refrigerant is the fluid that helps in cooling the air inside the room.
If there is a leak, the refrigerant will escape from the line and will not be able to cool the air inside the room. You will need to call a technician to fix the leak and recharge the refrigerant.
When a Frigidaire window air conditioner does not blow cold air, the most common reason is wrong settings. This can happen when you accidentally hit a button and change the temperature, the thermostat, or the fan speed.
If you do not know how to change the settings back, you can look in your owners manual for the correct settings.
Frozen evaporator coil
In this case, the problem is with Frigidaire window air conditioner since its evaporator coil has frozen over. This can prevent your Frigidaire window air conditioner from blowing cold air. So, the fix for this problem is to simply defrost your Frigidaire window air conditioner.
To do this, simply turn off your Frigidaire window air conditioner and unplug it. Then let it sit for about an hour so that the evaporator coil can thaw out. After that, simply plug in your Frigidaire window air conditioner and turn it on.
The air conditioner may not be properly vented to the outside, which can also cause the unit to not cool properly.
Frigidaire Window Air Conditioner Compressor Not Running
If your Frigidaire window air conditioner is not blowing cold air, it may be because the filter is dirty, the unit is not properly ventilated, or the temperature control is set too high.
1. Frigidaire air conditioners have filters that can become dirty over time and prevent the unit from operating properly.
2. The coils on the air conditioner can also become dirty and prevent the unit from cooling properly.
3. If the air conditioner is not properly sized for the room, it will not be able to cool the room properly.

4. The air conditioner’s fan is not working
If the air conditioner is not blowing cold air, then the fan is most likely not working. Contact a professional to troubleshoot this issue.
5. The cooling coils are covered in dirt
It is important that the cooling coils are kept clean and free from debris so that the air conditioner can operate properly. Clean the coils with a wire brush, or vacuum them to remove dirt, dust, and debris.
6. The filters are not clean
If the filters are not clean, then they will trap dust and dirt, causing them to overheat. This can cause the blower to burn out. Cleaning the filters regularly will keep them cool and reduce the chances of them overheating.
7. Poor Ventilation
In many cases, window air conditioner units that don’t heat are having problems because of bad ventilation. The reason why you see air conditioner units mounted in windows is that it’s the easiest way to get ventilation. Thus, you will have to ensure that the unit is mounted at the proper angle and not too close to the window.
The unit should be placed so that the expansion valve is pointing upwards. If you have the air conditioner mounted properly, the air conditioner should work.
Frigidaire Window Air Conditioner Won’t Turn ON
There are a number of reasons why your Frigidaire window air conditioner won’t turn on. First, verify that the unit is properly plugged into the wall outlet. If the unit is plugged in and still will not turn on, check the circuit breaker or fuse box to make sure that the circuit the unit is plugged into has not been tripped or blown.
If the circuit has been tripped or blown, reset the breaker or replace the fuse and try again. If the unit still does not turn on, it may be defective and will need to be repaired or replaced.
Blocked or clogged filter
If your air conditioner’s filter is blocked or clogged, it won’t be able to circulate the air properly. This can cause the unit to overheat and shut off. To fix this, simply clean or replace the filter.
There is likely a problem with the compressor. This is a common issue with window air conditioners. The compressor is located in the back of the unit and is responsible for circulating the refrigerant. If the compressor is not working properly, the air conditioner will not be able to cool the air.
Check condenser coil
If the air conditioner doesn’t turn on, it is most likely a problem with the condenser coil. The coil may be dirty, which will prevent it from getting enough airflow to function properly. You can clean the coil with a brush or with a can of compressed air. If the coil is still dirty after cleaning, you may need to replace it.
Low refrigerant levels
The problem can be with a low refrigerant level in the Frigidaire window air conditioner. There is a danger of freezing and also a risk of fire. You need to check the levels of the refrigerant in the air conditioner and make sure it is not too low.

Frigidaire Window Air Conditioner Not Cooling
There are a number of reasons why your Frigidaire window air conditioner may not be cooling.
The most common reason is that the unit is not properly sized for the room in which it is installed. If the unit is too small for the room, it will not be able to cool the room effectively.
The thermistor is located above the cooling coils and measures the air temperature around the cooling coils. This reading is sent to the main control board, which uses it to determine the rate at which the cooling coils should frost over.
If the thermistor is defective, the main control board will not receive the correct air temperature reading around the cooling coils. As a result, the cooling coils will not frost over at the correct rate, and the air conditioner will not cool properly.
To determine if the thermistor is defective, use a multimeter to test the resistance of the thermistor. The thermistor should have 10,000 ohms of resistance at 70 degrees Fahrenheit and 3,000 ohms of resistance at 50 degrees Fahrenheit. If the resistance is not within this range, replace the thermistor.
High Temperature setting
If the window air conditioner will not cool, check to see if the high temperature switch is on. This switch is located on the side of the unit, just below the control panel. If this switch is on, the air conditioner will not cool. Make sure the switch is in the OFF position.
Blocked condenser coil
