Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow it to cool.
User checks:
- Visually inspect the grill element inside the cavity for breaks, heavy pitting, or burn marks.
- Check that no foil or metal objects have contacted the elements.
Internal checks (experienced users):
- Remove the outer cover.
- Locate the grill and convection heater terminals and inspect wiring for burns or loose connections.
- Use a multimeter to test continuity of each element; an open reading indicates a failed element.
- Inspect the control board heater relays for signs of overheating.
Repair: Replace any open or visibly damaged heating element. If elements test good but E20 persists, the control board or relay may need replacement by a technician.
