What That Fridge Noise Actually Means (Buzzing, Clicking, Rattling, Squealing)
Customers describe fridge noises to us all the time, usually by imitating them. We’re pretty good at it now. Here’s the decoder.
Normal noises (leave it alone)
- Hum that comes and goes. That’s the compressor cycling. Expect it to run roughly a third to half the time.
- Gurgle or hiss after it stops. Refrigerant moving through the lines.
- Pop or crackle. Plastic and metal expanding as temperatures change.
- A drip or sizzle during the defrost cycle, a few times a day.
- Ice dropping. Obviously.
Noises worth checking
Rattling or buzzing from the back or bottom. Often the condenser fan or just a loose drain pan. Pull the kick plate and look. A fridge that’s shoved against the wall also buzzes because it vibrates on the drywall.
