Hello, my name is Rich and I am the owner-operator of Western Appliance Services. We do our repair work mainly in Boise, Meridian, and Eagle Idaho however, we do repair visits in Star and Kuna.
This picture shows what a defrost thermostat looks like. It’s the part with the two wires coming from it, one pink and the other orange. This part is what is installed on all refrigerators and its purpose is to prevent the evaporator heating element from getting stuck in the ON state. If that happens, it could be a fire hazard. As with many things sometimes they fail. The result of that failure is in the background.
The frost that has accumulated on the refrigerators evaporator is the direct result of the defrost thermostat going bad. Most refrigerators are set to go into a defrost mode every eight hours to prevent the buildup we see here. When the defrost thermostat is bad it does not allow electrical current to the heater element. When there is no automatic defrost then the frost will choke off air flow to the fresh food section of the refrigerator. This is something we see every couple of month. If you have a refrigerator problem, Western Appliance in Boise Idaho can fix it. Thank you,
Rich
