Possible Causes
Dry or worn fan motor bearings, Misaligned fan shaft, Excessive heat exposure degrading lubricant
How to Fix / Troubleshooting
Safety first: Unplug and cool the unit before inspection.
- Confirm source: Run the unit briefly and listen near the top to confirm the squeal is from the fan area, then unplug.
- Inspect motor: Access the fan motor and spin the shaft by hand. A gritty or squeaky feel indicates bearing wear.
- Do not lubricate permanently sealed motors: Most Ultima Cosa fan motors are sealed and not designed for lubrication. Temporary oiling is not recommended as it can attract grease and fail quickly.
- Replace motor: Install a new convection fan motor to eliminate the squeal.
