Defrost System

Automatic defrost after every eight hours of compressor run time is accomplished by utilizing a defrosttimer thermostat in the control box, a defrost bi-metal thermostat attached to the outlet of the evapotatorand a radiant electric heater suspended beneath the evaporator. (Fig. 4)

The bi-metal thermostat is attached to the outlet side of the evaorator coil tubing (Fig. 7) and opens at48°F to terminate the defrost heating. About 33 minutes from the start of the defrost cycle, the timerrestores operation to the compressor circuit. (Fig. 5) The bi-metal thermostat contacts close at 13°F,enabling the defrost heater to operate during the next defrost cycle.

The defrost heater is suspended on the right side and across the bottom of the evaporator. The defrostheater also provides warming to the defrost drain area to keep it clear during the defrost cycle.(Fig.6)

Both the refrigerator and freezer sections defrost automatically. However, clean both sections about once a month to prevent odors from building up. Wipe up spills immediately.

Cleaning your refrigerator

  1. Unplug refrigerator or disconnect power.
  2. Remove all removable parts from inside, such as shelves, crispers, etc.
  3. Hand wash, rinse, and dry removable parts and interior surfaces thoroughly. Use a clean sponge or soft cloth and a mild detergent in warm water.
  4. Wash stainless steel and painted metal exteriors with a clean sponge or soft cloth and a mild detergent in warm water. Do not use abrasive or harsh cleaners. Dry thoroughly with a soft cloth. For additional protection against damage to painted metal exteriors, apply appliance wax (or auto paste wax) with a clean, soft cloth. Do not wax plastic parts.
  5. There is no need for routine condenser cleaning in normal home operating environments. If the environment is particularly greasy or dusty, or there is significant pet traffic in the home, the condenser should be cleaned every two to three months to ensure maximum efficiency.
  6. Plug in refrigerator or reconnect power.
