We have a Kitchenaid Superba 27 Cubic Foot Side by Side Refrigerator/Freezer. The wife noticed that the Freezer Side was not Freezing today and the Refrigerator Side was also warming up. I checked the Coils aand cleaned the Dust off of which there was considerable amounts. The top of the Compressor was pretty Hot so I let it cool for 2 Hours. Plugged it back in and the Compressor would try to crank and you could hear the relay on the side drop out. The Unit is about 7 Years Old. Do you think the Relay, Compressor or smarter to replace the whole fridge. Thanks in advance.Sincerely,Steve Cook
