How to Fix / Troubleshooting
Safety first: Turn off the cooktop and allow it to cool for at least 30 minutes.
- Improve airflow: Ensure the cabinet under the cooktop is not packed with items blocking airflow. Maintain clear space around the cooling vents.
- Clean vents: Vacuum dust from intake and exhaust vents. Do not spray liquids into the unit.
- Check fan operation: With power restored, run the cooktop and listen for the internal fan. If it does not run or is very noisy, disconnect power, access the fan, and replace the cooling fan motor.
- Inspect heat sinks: If accessible, gently blow dust off the power board heat sinks using compressed air.
