Bought a home built in the 1960s with appliances that seem to be original. All work except for the Amana refrigerator. The motor turns on but it isn’t getting cool in either compartment. I would love to get this working again but don’t know where to start. My internet searches have yielded lots of info on restoring the appearance of vintage appliances but not much on the mechanical workings. Not opposed to calling a repair person (would it need to be something other than appliance repair?)…We have some electrical and mechanical experience and wouldn’t mind attempting a repair ourselves, but would only do that after acquiring at least some knowledge as we’ve never repaired a fridge before. Would appreciate suggestions on how to tackle this, where to look for info, etc. TIA!
