Possible Causes
Blocked ventilation openings, Failed cooling fan, Dust buildup on heat sinks, Faulty temperature sensor on power module
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the cooktop from the counter or opening the chassis.
- Check ventilation: Ensure that the cooktop's intake and exhaust vents are not blocked by cabinetry, insulation, or debris. Clear any obstructions.
- Inspect fan operation: Restore power briefly and start a low-power heating cycle. Listen for the cooling fan. If it does not run, disconnect power and inspect the fan for obstructions or seized bearings.
- Clean internals: With power off, use compressed air to blow dust from the fan, heat sinks, and power modules.
- Replace fan: If the fan is not spinning freely or does not run when powered, replace the cooling fan assembly.
- Module sensor: If the fan works and vents are clear but E4 persists, the temperature sensor on the power module may be faulty, requiring replacement of the induction power module.
