Oven display shows E12 and the unit may not complete preheat or may shut off unexpectedly.

Safety: Disconnect power at the breaker. Heating elements can retain heat; allow the oven to cool completely.

• Visual inspection: Remove oven racks and inspect the bake element (usually hidden under the floor panel or visible at the bottom). Look for blisters, cracks, or burn spots.
• Access element terminals: Remove the rear panel or interior bottom panel to access the element terminals. Check for burned connectors or loose spade terminals.
• Test element: With power off, disconnect at least one wire from the element and measure resistance. A typical bake element will show continuity (often 15–40 Ω). An open reading indicates a failed element that must be replaced.
• Inspect wiring: Check the harness from the element to the control board for heat damage or breaks. Repair or replace damaged wires.
• Control board: If the element and wiring are good but the oven does not energize the bake circuit, the bake relay on the control board may be defective and require board replacement.
