My refrigerator stops cooling and I heard clicking and buzzing from the back of it. I then bought new start relay and capacitor and replaced the old ones. But the problem remains (clicking, buzzing, no cooling). I checked other parts like condenser and evaporator fans. All of them are good and running well. Does it mean my compressor dead? But I checked the resistance of the compressor, the values look normal. What should I do? Any hints an helps are greatly appreciated!
