How to Fix / Troubleshooting
Safety: Turn off the power before accessing the blower compartment.
- 1. Inspect blower: Remove the blower door and visually inspect the blower wheel for debris or contact with its housing.
- 2. Spin test: Rotate the blower wheel by hand. Grinding or roughness indicates bearing issues.
- 3. Tighten set screw: If the wheel is loose on the motor shaft, tighten the set screw carefully.
- 4. Replacement: If the bearings are noisy or the wheel is damaged, replace the blower motor and/or wheel with Frigidaire-compatible parts. This is often a professional repair.
