OK so I "guessed"and ordered a relay/themostat and defrost timer, fuguring it was the relay. So would the relay make a clicking sound like that? The part that Sears sent me is a black relay, a cover and a wire connector unlike anything on mine. The original relay looks like it is inside a sealed housing ( I can see the 2 prongs of the relay, but it looks like it is sealed with the relay and overload inside it? It is the sealed piece that is held on with a wire which plugs into the compressor. I just powered it on again and the freezer gets to 5 degrees in and hour and 10 min, refrigerator made it to 42 degrees and then 25 min. later it shut off. Refrigerator stayed on longer as I didn't close up the back, thus compressor didn't overheat and shut off as soon? This is a symptom of the relay or would it be the overload?
Unfortunately the part Sears sent is not the unit pictured in my original schematic and actual part. I received a black cover, a seperate black relay switch and a wire that is not compatable as it looks like the opposite end goes to the fan actually. This part totally confused me as I was expecting a one piece unit like I removed. I was thinking I should try to order an overload/relay/start capacitor from PartSelect instead and see if I get a plug and play unit altogether for this? I really don't want to buy a new refrigerator, I just want this one to work again and was willing to try the relay as compresor turns on but seems as though it overheats and shuts off once it gets unit up to temp range. I figured since the repair person was a waste of time I would give it a try myself. I have fixed a washer and a dishwasher before, so not afraid of trying just not sure how to troubleshoot at this point.
I guess that means that I will need to somehow disasseble this original unit so that I can see and access this white overload piece, then reassemble it with the new black relay and put in this cover over the 2 pieces so that I have plug holes in the shape of a triangle. I can't visualize, so this should be fun. Truly, the original looks like the 3 holes in the triangle you refer to, are actually molded into this original housing piece. Ok so you opinion is that since it all comes up to temp and shuts off that the compressor is overheating and therefore it is the relay/overload/start or the compressor itself? And the compressor is too costly for a unit this old if the relay start/overload doesn't resolve the issue.
