Possible Causes
Failed cooling fan, Blocked ventilation, Overheating of power module heat sink, Faulty temperature sensor on heat sink
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the cooktop to cool before inspection.
- Check ventilation openings: Ensure that intake and exhaust vents under the cooktop are not blocked by cabinetry, insulation, or stored items.
- Inspect cooling fan: Remove the cooktop and bottom cover. Spin the fan by hand; it should move freely. If stiff or noisy, replace the fan.
- Clean dust: Use a vacuum and soft brush to remove dust from the fan, heat sinks, and electronics.
- Verify fan operation: With power restored (only if you are qualified), start a low-power heating cycle and confirm the fan runs. If not, test for supply voltage at the fan and replace the fan or control board as needed.
