Refrigerator Vibration And Backflow
I have a domestic refrigerator which periodically starts to vibrate and make a lot of noise immediately after the compressor shuts down. The compressor vibrates agressively for a couple of minutes after the compressor shuts down. Unplugging the refrigerator confirms that the compressor is not running during this vibration and noise event. Do I assume correctly that a compressor discharge check valve is failing to seat and allowing reverse flow of refrigerant through the compressor?
Thanks.
