I have a 1999 frost free hotpoint fridge that is not cooling. The compressor seems to be running. I pulled off the relay and overload and put the ohm meter on them. I got no reading. Does this mean they are ok? I also checked the 3 leads on the compressor by checking each lead with the common grounded to the compressor itself, and got no reading. I think that means the compressor is good. where do I go from here? Any help would be great!
