Possible Causes
Open-circuit upper grill element, Burnt wiring to grill heater, Faulty grill relay on control PCB
How to Fix / Troubleshooting
Safety first: Disconnect power and ensure the oven is cool before accessing elements.
- Visual check: Inspect the upper grill element inside the cavity for breaks, blisters, or burn marks.
- Continuity test: Access the rear of the oven and disconnect the grill element terminals. Measure resistance with a multimeter. An infinite reading indicates a failed element.
- Inspect wiring: Check the wires from the element to the control board for signs of overheating or loose connections.
- Replace grill element: If open, install a new Hitachi upper grill heater element. Ensure all terminals are tight and insulated.
