How to Fix / Troubleshooting

Safety first: Disconnect mains power and allow the oven to cool before testing elements.

Steps to diagnose:

Identify failing modes: Test each cooking mode and note which ones do not heat.
Map modes to elements: Refer to the user manual or wiring diagram (if available) to see which elements are used in each mode.
Test affected element: Access and measure resistance of the element associated with the failing mode. Replace if open.
Inspect connectors and wiring: Check for burnt or loose connectors on the affected element and at the control board output.
Control board relay: If the element is good but never energizes in its mode, the corresponding relay on the PCB may be faulty. Replace the main control board.
Test: After repairs, verify that all modes heat correctly.

Oven interior light and fan turn on, but heating only works in some modes (e.g., grill works but bake does not).
