Whirlpool Worn or Dry Motor Bearings

Whirlpool garbage disposal runs but makes a high-pitched squealing or screeching noise.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aging motor bearings, Water intrusion into bearing area, Misaligned motor shaft, Debris caught near bearing surfaces

Safety first: Turn off power before inspecting.

Check for foreign objects: Inspect the grinding chamber and remove any debris that could be rubbing.
Short test: Restore power and run the disposal briefly with water to confirm the noise is from the motor, not from loose items.
Do not lubricate internally: Whirlpool disposal motors are sealed; do not attempt to oil internal bearings.
Replace unit: Persistent squealing indicates bearing failure. The correct repair is replacement of the disposal assembly.
