I got a sub zero certified serviceman come over to take a look. Without using any meter except for pushing the compressor around and hearing knocking sound, it was concluded that I needed a new compressor. While the compressor is still under warranty, the labor cost and disposal cost added up to a significant amount. I’m not sure if I a wool got pulled over my head, but I’m not certain that the compressor was the problem, but more like the capacitor? Any advice? It is a 736ct Model.
