My refrigerator makes a intermittent loud buzzing sound. It happens for about 5 to 10 seconds, every minute or so. I have an Amana Refrigerator with a bottom freezer
, Model # XXXXX SER# XXXXX After a few days of this, everything in the freezer
melted and it seemed as the fridge part was also not as cool. From posts on the internet, it seemed the most probable cause was either an overload relay that is attached directly to the side of the compressor, or the compressor itself.
I purchased and changed the relay. Plugged the fridge back in, and it made the same buzzing sound and did not cool at all. Figured that it's now the compressor. While browsing (google) more of the same topics, I came across one solution that had an extra note to let the fridge stay unplugged for a while before restarting to let the pressure in the compressor equalize.
I let it sit overnight, and in the morning, plugged the fridge back in, and added a small tupperware container of water in the freezer to see if it would freeze. The Fridge initially made the same buzzing sound for a few times, but then it seemed to quiet down to a normal sounding fridge. Amazingly, after about two hours, the water in the freezer was frozen.
After about 5 hours, we started to hear the compressor making the same intermittent buzzing sound again, and the water in the freezer eventually melted again.
PS: We are again currently letting the fridge sit unplugged overnight to see if it repeats to turn on again in the morning.
