This week we look into the world of refrigeration. Defrost problems are frequently the source of service calls. Often these call can boil down to the "defrost trio". That would be defrost timers, defrost heaters, or defrost thermostats.
Slightly less common, being used in over 199 GE/Hotpoint models as well some Kenmores, the WR51x10031 has a shorter glass tube and only one glass tube and bracket configuration. Like the WR51x443 it comes equipped with wiring harness and defrost thermostat.
While we are talking about frost in the freezer, lets look at making that freezing water into ice cubes. For this there are, of course, a variety of icemakers. Nine older icemaker models from the Electrolux product family can all be replaced by the 5303918277. It has four round female connectors at end of wire harness and comes with adaptor that converts the harness to three round female & one round male connectors.
Making ice requires freezing temperatures. To determine the temperature on many modern refrigerators, a thermistor sensor is used in conjunctions with a computer board, The WR55X10025 is a very common thermistor in GE, Hot Point, and Kenmore refrigerators. Many models use several of these sensors on one machine making this a good choice for truck stock.
The relay/overload is used to complete the electrical circuit for the compressor as well as providing a surge of electricity to help start the compressor. The RO81 is for use on many older 1/12-1/3 HP compressors.
