Possible Causes
Overheated induction coil, Blocked cooling fan or vents, Failed temperature sensor on coil, Continuous high-power operation without ventilation
How to Fix / Troubleshooting
Safety first: Turn off the cooktop and allow it to cool completely. Disconnect power before removing panels.
- Ventilation check: Ensure that the cooktop's underside vents are not blocked by insulation, drawers, or stored items.
- Cooling fan operation: Listen for the internal fan when the cooktop is in use. If the fan does not run, access the underside and test the fan motor. Replace if not operating.
- Clean dust: With power disconnected, gently vacuum dust from the fan and heat sinks to improve cooling.
- Sensor/coil inspection: Inspect the temperature sensor attached to the induction coil. Ensure it is firmly attached and wiring is intact.
- Replace faulty parts: Replace a failed cooling fan motor or coil temperature sensor if they test defective.
Repeated E2 errors after cooling indicate a cooling system or sensor problem that should be addressed before further use.
