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.
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.
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.
When your compressor doesn't kick on, one common culprit might be a faulty pressure switch. For instance, if the pressure switch is stuck in the open position, it may not send the necessary signal to the compressor, preventing it from working as expected.
Turn off the refrigerator and freezer from the control panel. After unplugging the refrigerator, turn off the fridge and freezer using the control panel inside the fridge. To do so, set the controls to “zero" or switch them off entirely. Once you're done, you can plug your refrigerator back into the wall socket.
Be sure to check the electrical outlet, thermostat and airflow around vents. Cooling problems can also be caused by dust on condenser coils, faulty gaskets, clearance space around the refrigerator, a broken or stuck condenser fan or a faulty circuit board.
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.
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.
One cause is that the temperature control thermostat is not working properly, forcing the freezer to run constantly to try and meet the correct temperature. If this is the case, you can try resetting the thermostat or replacing it altogether.
Some causes may be simple, like crowding items or dirty condenser coils, and other causes may require professional repair, like a broken evaporator fan.

Problems with the freezer's electronic control board, cold control thermostat, defrost timer, or compressor can all result in a freezer that does not run or runs improperly.
How long does it take a freezer to reset? Walking through the steps of resetting a freezer should only take a few minutes, but it can take up to 24 hours for the freezer's temperature to stabilize upon resetting.
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.
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.”
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.
