For the symptom you selected, these are the most common parts or causes, ordered by the likelihood of fixing the symptom.
If the freezer does not get cold the condenser coils might be dirty. The condenser coils need cleaning about every six months to a year. If they get coated with dirt, dust and lint they will not be able to dissipate heat effectively which will affect the cooling. Some freezers have the condenser coils in the walls of the unit. These are not accessible and do not need to be cleaned.
If the freezer does not get cold the evaporator fan motor might have stopped working. On the back wall of the freezer, normally behind a panel which can be removed, there is a small fan. This fan draws air over the evaporator cooling coils and moves it around inside the freezer. If the freezer does not get cold, the evaporator fan motor should be checked. Often the fan motor will not run when the door is open, activate the door switch for the fan to work. If the evaporator fan motor doesn't run when the freezer is cooling and the door switch is activated, it should be replaced.
If the freezer does not get cold, the start relay may be defective. The start relay is a small device mounted to the side of the compressor. It provides power to the start winding of the compressor for a short time and then to the run winding. If the start relay is defective the compressor may run intermittently or not at all and then the freezer does not get cold. The start relay should be replaced if defective.
If the freezer evaporator coils ice over, the freezer does not get cold enough. Several times a day the defrost heater assembly turns on for a few minutes to melt away any frost or ice that may have accumulated on the freezer evaporator coils. If the defrost heater assembly has burned out, the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling to the freezer. The most common cause for this condition is a problem with the defrost system.
The freezer has a condenser fan motor. If the freezer does not get cold, the condenser fan motor may have worn out, burned out, or may have something caught in the blades preventing it from spinning. The condenser fan motor is accessed from the back side of the freezer, near the bottom. An access panel may have to be removed to service it. The condenser fan motor is relatively inexpensive and easy to replace.
If the freezer does not get cold the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. Try rotating the temperature control thermostat all the way from stop to stop and listen for a click. If there is a clicking sound the thermostat is probably good. If not, remove it and check it for continuity. It should have continuity when the freezer is calling for cooling.
If the freezer does not get cold the user control and display board might be defective. The user control and display board allows power to flow through to the compressor, evaporator fan and condenser fan. This is not a common problem and is often misdiagnosed. Before replacing this board check other, more common components first.
If the freezer does not get cold, the main control board may be defective. The main control board is often misdiagnosed, so be sure to check for other causes. If the main control board is defective it will have to be replaced, it is not repairable.
If the freezer does not get cold the compressor might be defective. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. There are several other components which are more likely to be defective if the compressor doesn't work. If the compressor itself is defective a licensed professional will have to do the repair.
