Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug and cool before inspection.
- Confirm source: Run the unit briefly and listen near the top/rear to confirm the squeal is from the fan area.
- Inspect fan alignment: With power disconnected, check that the fan spins freely and is centered in the guard.
- Do not lubricate excessively: Most small appliance motors are not designed for user lubrication; adding oil can attract dust and fail quickly.
- Replace motor: If squealing persists and the motor feels rough or has play in the shaft, replace the convection fan motor with a Crux-compatible part.
