Tips for troubleshooting common freezer problems, and how to know when to throw in the towel and call a professional appliance repair company.

 When your freezer stops working, whether it's a freezer and refrigerator combo or a stand-alone freezer, you need help quickly before food goes to waste.  Most freezer repair issues will require an appliance repair service, but it may help to know the major working parts of your freezer when you make that repair call.

Automatic Defrost

Some freezers have an automatic defrost option. If it's not working, examine the thermostat, defrost timer and defrost heater. If none of these appear to be malfunctioning, call a professional.

The Compressor

The compressor is the part of the freezer that decreases the volume of the gas and, in turn, increases the pressure. If your compressor is bad, your freezer may not cool or it may not work at all.

The Condenser

The condenser is the component of the freezer that condenses a vapor into a liquid, producing cold air, so problems with the condenser may lead to the freezer not cooling properly. The condenser has a fan, which may be dirty, which should be cleaned periodically.

The Evaporator

The evaporator turns a liquid into a gas. Generally, problems with the evaporator can cause the unit not to cool.
