Weekly Wednesday Stock Ideas

Every week at W.L. may we have several items we feature as good parts to consider adding to your stock. These parts also have special pricing available. For pricing details, ask your account representative for more information.

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.


This popular GE defrost heater, WR51x443,  is used on over 205 GE, Hotpoint models and many Kenmore models as well It is composed of two glass tube of approximately 10 inches with mounting brackets, wire harness and built into the harness defrost thermostat.


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.

Unfortunately, over time, some parts are discontinued by the original appliance maker. When that happens with defrost thermostats, some people turn to this 50 degree general purpose clip-on defrost thermostat, SLT50.


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.

A frequently used accessory (so much so that many guys buy the 12 at a time), the BPV31 is known as the "Bullet Piercing Valve". Designed to pierce copper tubing, this part is a "must have".


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 compressor is the heart of the refrigeration system. It is important that the right size of compressor with the right refrigerant is used. Also, without proper certification, the EPA does not allow sealed system work. If all the conditions are right, however, this 1/4+ HP compressor might fit your needs.


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.

To really get the compressor going some models include a capacitor for the compressor. Appliance makers traditionally have included a capacitor until recently when energy efficient designs have bypassed that need. The nice thing about the URCO810 is it is a "three-in-one" relay, capacitor, and overload that can be used on 1/12 to 1/5 HP machines with OR without a built in capacitor.
