My refrigerator makes a noise periodically that sounds like a ping pong ball bouncing 3 times. It seems to happen when the motor stops after it has been running to cool it down. This has been going on for some time and the unit works fine otherwise. Should I be concerned?
No. This is not a great deal. Your compressor is switching off at times which makes the sound, but it is a power saving technique adopted by the manufacturer. It is certainly not a problem.
