It had the compressor replaced about 3 years ago, I can fill it running but my gauges won’t work I guess it is because it is a flamable refrigerant. the condensor and evaporator fans are running. I replaced the thermister on the compressor but it didn’t help Idon’t know how to test the other components. It has a small computer on the top but I couldn’t find a way to test the other components.
replaced the thermister on the side of the compressor.
