Possible Causes
Failed cooling fan motor, Blocked air intake or exhaust vents, Fan wiring harness disconnected, Faulty fan driver circuit on control board
How to Fix / Troubleshooting
Safety first: Disconnect power and ensure the cooktop is cool before accessing the underside.
- Inspect vents: Check under-cabinet and front/rear vents for dust, insulation, or stored items blocking airflow. Clear all obstructions.
- Check fan blades: Access the cooling fan and ensure the blades spin freely by hand. Remove any debris.
- Test fan motor: With a multimeter, check for continuity across the fan motor leads. An open circuit indicates a bad motor. Replace the fan assembly.
- Verify wiring: Ensure the fan connector is fully seated on the control board and that wires are not pinched.
- Control board: If the fan and wiring are good but the fan never runs, the control board may not be powering the fan and may need replacement.
