Normal Sounds vs. Problem Sounds

First, it’s important to know which sounds are considered normal:

  • Soft humming or fan noise (especially during cooling cycles)
  • Clicks when the defrost cycle starts or ends
  • Occasional pops or gurgling as refrigerant moves through coils

Sounds that may indicate a problem include:

  • Loud rattling, grinding, or buzzing from the back or bottom of the unit
  • Repeated clicking without startup (could indicate relay or compressor issues)
  • Loud fan noise from inside the fridge or freezer compartment

Loose or Vibrating Parts

Many refrigerator noises stem from simple vibrations:

  • Make sure the appliance is level and all four feet are stable
  • Check for loose drip pans or covers underneath
  • Reorganize food items to eliminate internal rattling

Condenser or Evaporator Fan Issues

If the noise is coming from inside the fridge or freezer, it could be a failing evaporator fan. If it’s coming from the back or bottom, the condenser fan may be to blame.

  • Fans can collect dust or ice and start to whine or grind
  • Worn fan motors can cause vibration or squealing sounds
  • Cleaning or replacing fans usually requires partial disassembly

Compressor Noise

The compressor is responsible for circulating refrigerant — and while it does make noise, excessive or clunking sounds may signal a problem.

  • Older compressors tend to be louder and more erratic
  • Clicking without startup may point to a failed relay or capacitor
  • If the fridge isn’t cooling along with noise, call for immediate service

When to Call a Technician

If your refrigerator is suddenly much louder, producing irregular noises, or disrupting your kitchen routine, it’s worth having a professional take a look. Fan motors, compressors, and electrical components should be handled with care — and a trained technician can identify the issue quickly and safely.
