Possible Causes

Worn upper or lower bearings, Lack of lubrication due to age, Misalignment of motor shaft, Debris lodged in bearing area

How to Fix / Troubleshooting

Safety first: Turn OFF power at the breaker. Do not continue to run a squealing motor as it may seize.

  • Step 1 – Check for chamber obstructions: Ensure no foreign objects are scraping the plate or chamber walls.
  • Step 2 – Listen carefully: Briefly run the unit with water and identify if the noise is from the motor area rather than the chamber.
  • Step 3 – Inspect exterior: Check for signs of overheating or misalignment, such as rubbing marks on the housing.
  • Step 4 – Replace unit: Internal bearings in sealed Teka disposals are not serviceable. Continued use can lead to motor failure and tripping breakers; replacement is recommended.
