I have a kenmore side-by-side refrigerator that is not running cold. The compressor is making a buzzing sound every five to ten minutes while running,I believe the compressor is trying to start up. I have replaced the start relay and the capacitor carries a good reading. After replacing the start relay the compressor continued to make the buzzing sound until finally it went away. I let the refrigerator run a bit, was not cooling off. I unplug the the refrigerator waited a bit plugged it back up and the compressor started running all is well the refrigerator cooled itself off. The following day the compressor started making the same sound again and the refrigerator was no longer cool anymore. All components are working fine on the refrigerator except the compressor. Could someone please help me out with my question. Thank you!
