Sears Kenmore Defrost Thermostat

Sears Kenmore Refrigerator(Model#596.75529400): Not cooling properly. I found the evaporator, that’s located inside the freezer behind the back panel, all frosted up heavily. Before you defrost it always ohm the defrost thermostat for continuity. I did a ohm test on it for continuity with an ohm meter, found no continuity at all. Installed new defrost thermostat, worked great!

Sears Kenmore Start Device Relay

Sears Kenmore side by side refrigerator(model#106.50542001): Not cooling, pulled the refrigerator out from the wall, then removed the lower back access panel, unplugged the refrigerator first, then removed the start device relay from the side of the compressor and shook it, it rattled alot. Whenever it rattles like that, its always broken inside.
