Oven will not heat in any mode, display and oven light work normally

Safety first: Disconnect the Etna oven from mains power by switching off the circuit breaker or unplugging. Verify no power is present before removing any panels.

• Check heating elements visually: Remove the oven racks and inspect the lower bake element and upper/grill element for blisters, cracks, or burn marks. A broken or bubbled sheath usually indicates a failed element.
• Test elements with a multimeter: Access the rear of the oven, remove the back panel, and disconnect the element terminals. Measure resistance; most Etna oven elements should read between 15–60 Ω. An open circuit (OL) means the element is bad and must be replaced.
• Inspect wiring harness: Look for burned connectors or melted insulation on the wires going from the main PCB (control module) to the elements. Repair with high‑temperature oven wire and proper crimp terminals if damaged.
• Check main PCB relays: If both elements test good, inspect the main control board for burned or cracked solder joints at the heater relays. If relays are visibly burned or the board smells scorched, replacement of the main PCB is recommended.
• Reassemble and test: After replacing any faulty element or PCB, reassemble all panels, restore power, and test in conventional bake and grill modes to confirm heating.
