How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
- Identify fan type: Determine if your Hisense oven uses a standard AC fan or an electronically controlled multi-speed fan.
- Inspect fan and module: Access the fan and any attached control module. Look for burnt components or melted connectors.
- Test motor: If possible, test the fan motor by applying appropriate voltage directly (only if you are qualified). Replace the motor if it does not run smoothly.
- Check wiring: Ensure all connectors between the fan, module, and main board are secure.
- Replace module/board: If the motor is good, replace the fan speed control module or main control board as indicated by the service manual.
