Before you call an appliance repair technician about your malfunctioning freezer, you'd like to see if the problem is something you can fix yourself. Some issues that cause the freezer to stop working properly are relatively easy to resolve, while others are best handled by a professional. Go through a short checklist of symptoms and determine whether you need to have a technician stop by:
Tasks You Can Do
Check the Power
If the freezer has stopped running and the light is off, check the power to the appliance. If you've never had an electrical issue with the freezer before, you may not have thought to see whether you have a blown fuse or circuit breaker.
If there are no problems with the fuse or breaker, test the outlet for voltage. You may need to call a technician if you don't have a voltage tester and don't know someone else who does.
Clean the Coils
If the freezer is still running but is not keeping the food and beverages frozen, unplug the freezer and check the evaporator coils. These coils are hidden behind a panel; you can find the diagram in your owner's manual. If you can't find your owner's manual in the house, you should be able to access a copy online.
Although the coils are relatively protected, they can still accumulate dust and debris, which may cause them to freeze up with ice. You'll need to keep the freezer unplugged and allow it to defrost. When the coils are dry, vacuum the dirt up with a crevice or brush attachment.
Tasks for a Technician
Have the Thermostat Replaced if Necessary
If the freezer is running and the coils are clean and not coated with ice, the problem may be a faulty thermostat. A technician can check the thermostat and replace it if it has worn out.
Get Refrigerant Leaks Fixed
Rather than a faulty thermostat, the problem may be low refrigerant. A technician will look for a leak and make necessary repairs as well as add more coolant.
Have the Compressor Replaced
If the freezer is not running and the power is OK, or if the freezer is working fine but is making strange noises, the compressor probably needs to be replaced.
A typical symptom of a compressor that is going bad is a clunking noise each time it shuts off. A freezer can run for months in this condition, but it will eventually fail and do so abruptly. If that won't be a crisis situation, you may simply want to wait until that happens before deciding what to do. Compressors are electric motors, and they are not cheap. A technician may advise you to get a new freezer rather than a new compressor.
Do what you can to get your freezer working again. If you can't fix the problem, call an appliance repair technician for prompt and effective diagnostics and service. To learn more, contact a company like Certified Appliance with any questions you have.
