What Does a Bad Refrigerator Compressor Sound Like?

If you listen hard enough, your refrigeration system is trying to talk to you. Yet, it can be difficult to know whether it is telling you “I’m working hard over here!” and “Help me!” This is because systems like this make noise quite often, and they’re usually not a cause for concern. How can you tell the difference? What is a good noise and what is a bad noise?

Grinding, Scraping, or Knocking

There could be an obstruction in one of the system’s fans. There is a condenser fan located in the bottom of the refrigerator and an evaporator fan in the freezer compartment. You will want to remove any debris that may be blocking the fan blades as well as inspect the fan for broken parts that need to be replaced before you leave shore.

Sizzling

Don’t worry! While a sizzling sound might sound scary, it’s likely not a cause for concern. It is probably just water dripping on the defrost heater.

Recurring Clicking, Buzzing, or Vibrating

The sound is probably the icemaker attempting to make ice but not being connected to a water supply. Either connect it or shut it off altogether so the sound will stop.

Rattling

The cause of the rattling noise may be as simple as the sides or back of the fridge touching another surface, like a wall or kitchen cabinet. Pull the fridge out a few inches and see if it stops. Otherwise, the drain pan below the refrigerator may have come loose. 

Loud Humming

Refrigerator compressors make low humming or buzzing sounds as part of their normal operation. A low sound is not a cause for concern. That being said, if the refrigeration system‘s noise gets louder and louder to the point where you can hear it from the other side of the boat, you’ll need a replacement part.
