Our Kenmore was purchased in Feb '08 specifically to run in the garage. Some months ago it stopped cooling though it continued to run. A repairman has told us the relay burnt out. Is this a problem others...
Relays burn out from trying to restart a compressor that's under load or bad. The problem is high amp draw and most relays can take only take so much abuse before they give it up. Here's what I think.
1. Your garage is unheated and in the winter it's very cold. Refrigerant will migrate to the coldest spot and if the garage is colder than the inside of the freezer, you are slugging the compressor with liquid refrigerant. This causes the relay to overheat and burn out. It's even worse for the compressor!
2. Your garage has poor ventilation and gets extremely hot in the summer. Excessive heat will cause a refrigerator to have to start under load every time it tries to remove heat from the inside of the cabinet. Most refrigeration systems are designed to operate at 90deg. tops. Over that they lose efficiency. If it gets over 90deg and stays there for long periods it will cause the compressor to start under a high load every single time. Even worse, if the refrigerator is coming off a defrost cycle the load will be even higher. This will cause the relay to overheat and burn out prematurely.
Relay's are an easy fix for me but for you it'll be a little confusing. There are three poles on the compressor labeled "C", "S" and "R" which stand for common, start and run. Replacement relays come in two types for fridges, (a) electronic and (b) solenoid type. The solenoid type is the easiest to replace because it only goes on one way. The electronic has three wires and they must go on the correct poles. The poles are as follows. From the upper left or top and going clockwise, common, start run. The wires should be common (black), start (white) and run (red)..Read the instructions first to make certain the the wires are the correct colors for the correct poles. (Find the "C" pole first then go clockwise!)
Personally, I'd check your warranty to see if it's covered first then have a good refrigeration repairman fix it. Afterwards I'd make certain that the temperature in your garage stays within 0-80 degrees respectively. Keep the condenser (the grill that's either behind the unit or under it) clean and clear. Never use any sharp objects to clean the condenser or evapoartor!
One other thing. There is supposed to be an overload with the relay. That could also cause the fridge not to cool. It's purpose is to shut down the compressor if it gets too hot or, open the relay's electrical circuit if the relay draws too many amps. My money's on the relay but you best change both.
I hope this helps.
