How to Fix / Troubleshooting
Safety first: Unplug the grill before accessing the fan. Do not insert fingers into the fan while it is connected to power.
- Step 1 – Access fan: Remove the side or rear panel to expose the combustion fan assembly.
- Step 2 – Inspect blades: Check for bent or damaged blades and remove any debris (insects, ash, foil pieces) lodged in the fan.
- Step 3 – Tighten mounting hardware: Ensure all fan mounting screws and any brackets are tight. Loose mounts can cause rattling.
- Step 4 – Spin test: Rotate the fan by hand. Roughness, grinding, or excessive play indicates worn bearings.
- Step 5 – Replace fan if needed: If the motor is noisy or the blades are badly bent, replace the combustion fan assembly with a Cuisinart‑compatible part.
