If we could change an old and familiar proverb to meet our needs about appliance repair, it might go “An ounce of prevention with proper refrigerator maintenance is worth a pound of savings in refrigerator repair”. I’m not sure that would make the next revision of the book of Proverbs but I think the point is made. Since a refrigerator usually works 24/7 you’re bound to face the challenge of refrigerator repair sooner of later. The best way to put off refrigerator repair as long as possible is by carrying out proper refrigerator maintenance. Let’s approach these situations one step at a time by finding out:
- What are the parts of a refrigerator and what do they do;
- How to conduct proper refrigerator maintenance; and
- What steps to take in refrigerator repair.
The Parts of a Refrigerator
The basic parts of a refrigerator are a condenser coil and an evaporator coil. They’re what make the refrigerator chill or freeze the food and beverages you store in the fridge. A compressor and motor circulate a liquid coolant through these coils. The condenser cools the liquid which flows on to the evaporator. The evaporator coil with the liquid in it cools the air in the unit.
In most modern refrigerators, there is a heating unit which automatically turns up the temperature to melt the frost that builds up in the refrigerator. Once the frost melts, the thermostat turns the heater off and switches back to the cooling temperature. This keeps the refrigerator frost-free.
3 Easy Tips to Maintain your Sub-Zero
- Proper refrigerator maintenance starts with putting it in the right place – away from heat sources like direct sunlight, radiators and stoves. The next task is to keep the refrigerator level with the floor. This prevents the door from not closing properly and letting the cold air escape.
- The next point in good refrigerator maintenance is to keep the coils clean. Dust coating the condenser coils makes the refrigerator work harder and shortens its life. Every three months or so, vacuum or sweep away the dust from the condenser coils. The coils are located either behind or under the refrigerator, depending upon the model.
- Keep the cool air in the refrigerator by checking for holes, gaps or worn out gaskets. Test the tightness of the seal by closing the fridge door on a piece of paper. If you can easily pull out the paper, then the door needs to be adjusted or the seal replaced.
Refrigerator Repair Checklist
- Before doing any repair work, be sure to first unplug your Sub-Zero refrigerator and inspect the power cord and see that it is not defective.
- Check to see if the motor has a capacitor. If it does, discharge the capacitor first before undertaking any repairs so you don’t get a severe electrical shock.
- The parts that control the refrigerator are located at the top so you will need to disassemble the refrigerator. The motor compressor, condenser coil and condenser fan are at the bottom of the unit.
- After disassembling the fridge, you can remove and replace the defective parts, except for the condenser and evaporator coils. You can either unscrew the parts or pry them loose from their brackets. The condenser and evaporator coils are sealed units.
