Refrigerator Noise – Quick FAQ

Yes. Clicking and gurgling are usually normal. Clicking often comes from relays or defrost timers, while gurgling is from refrigerant and water moving through internal lines. If the sounds suddenly get much louder or the fridge stops cooling, schedule a service call.

Buzzing may be the icemaker filling with water, the dispenser motor, or the compressor running. Short buzzing during normal operation is typical. If the buzzing repeats often, is very loud, or happens with no water connected, it should be checked by a technician.

Call a technician if the noise is new, very loud, continuous, or comes with other symptoms like warm food, leaks, burning smells, or error beeps. These signs can indicate a failing fan, compressor, or other critical component.

Sometimes, yes. Ignoring grinding, scraping, or repeated clicking can lead to bigger failures and more expensive repairs. Early diagnosis often saves money and prevents food loss.
