How do you test a defrost control unit,temp.thermostat my frig seems to cool fine but the fans runs to much,also i'm getting a slight and a short interference back to my electrical main panel and feeds back to rest of the house,all my grounds are tight,i get a short buzzing noise threw my phone only during this cycle, this only does it when the frig go's though a short cycle the fans can be running and i can hear a clicking sound when i put my ear on the side of the frig not a steady clicking 2or3 times,i been told that you should have a surge protector on your frig count of power failures,which we do once in a while...also the inside of the frig can freeze some things close the back...thank you for your help
