Possible Causes

Open-circuit grill element, Open-circuit convection heater, Faulty heater relay on PCB, Burnt wiring to heating elements

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.
