How to Fix / Troubleshooting
Safety first: Unplug the smoker before accessing the fan.
- Access and inspect fan: Remove the rear panel or internal shroud to view the fan. Clear any foil, food, or grease blocking the blades.
- Spin test: Rotate the fan by hand. If stiff or seized, replace the fan motor assembly.
- Check wiring: Ensure the fan connector is secure on the control board and wires are intact.
- Test operation: After reassembly, run the smoker and listen for the fan. If it still does not run and the motor tests good, the control board’s fan driver is likely faulty and the board should be replaced.
