Shutting off the power to the refrigerator will give all of its systems—including the compressor—time to reset. Power down your refrigerator by unplugging it from the wall or shutting off the circuit breaker connected to the fridge. Leave the unit unplugged for five to ten minutes.
Compressor Sounds: When the freezer is running, listen for a humming sound from the compressor. If it's silent or making clicking noises, it could indicate a problem. Fan Operation: Check if the interior fan is running. If not, it may be a sign of an issue. Ensure the thermostat is set to a cold enough temperature.
Wait several minutes, then plug the freezer back in and restore power to the control panel switch. Set your freezer to your preferred temperature settings and allow it to cool. It can take up to 24 hours for its temperature to stabilize, depending on how long the unit was without power.
The location of the reset button on your compressor can vary depending on the model and manufacturer. Typically, it is located on the motor or near the motor housing. Look for a small red or black button that is often labeled “reset.”
If your freezer is not cold, the problem may be caused by a broken condenser fan motor. The condenser fan draws cool air through the condenser and over your freezer's coils. If this fan is broken, your freezer's inner temperature will rise, and the compressor will overheat.
Depending on the model, this may take more than 24 hours, so be patient. If your compressor will not start again, try adjusting the controls to colder settings to see if it will start. Wait for some time, as the refrigerator could be in the midst of a defrost cycle, and the compressor won't run when it is defrosting.
To reset your reciprocating air compressor, allow time for the compressor to cool down and then push the reset button before attempting to turn the unit on again.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
Your compressor will usually last 8-10 years. If you start having issues with your compressor before this time frame, it might be worth looking into options for repair, but if it's hitting the average lifespan, it might be more worth it to replace entirely.
Start relay or controller: When faced with a freezer compressor not starting, the compressor start relay (or controller) is often the culprit. Located on the side of the compressor, the controller energizes the start windings and typically contains overload protection.
On average, they can last between 8-10 years, which still varies. There are many variables such as the type of compressor and maintenance schedules that can affect compressor failure rates.
This button is often located near the compressor. Press and hold: Press the reset button for about 3 seconds. This action will initiate the reset process for the compressor. Restart: After resetting the compressor, turn the power back on to the AC unit.
Overheating is a common cause of compressor failure, and there are many factors at play. If direct sunlight falls on your outdoor unit and there is inadequate ventilation around it, it makes your unit's compressor overheated. High voltages can also damage the motor causing the compressor to overheat.
Reasons your freezer isn't freezing may include:
Dirty condenser coils. Malfunctioning evaporator fan. Broken start relay. Defective electronic controls.

A Frigidaire freezer not freezing is most often caused by dirty condenser coils, a worn-down gasket, or a faulty thermostat, which result in higher temperatures inside the refrigerator and inadequate airflow.
You Hear Unusual Noises
A hum or a slight buzz is typical, but if your refrigerator starts making strange or loud noises, the compressor might be struggling. Professional Repair Required: Compressors have numerous components, and diagnosing the source of the noise can be complicated.
The noises could also mean that your freezer's evaporator fan isn't working correctly; if this is the case, you should repair or replace it soon. If the evaporator fan is damaged or old, you may notice a loud buzzing or clicking noise. Your freezer might also run less cold than usual.
