Possible Causes
Open bake element, Loose or burned bake element terminals, Failed bake relay on control board
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker. Confirm the oven is cool before touching any components.
- Inspect the bake element: Open the oven and locate the lower bake element (exposed or hidden under the floor panel depending on model). Look for blisters, breaks, or burn spots.
- Check connections: Remove the rear panel to access the element terminals. Inspect for burned or loose spade connectors. Tighten or replace damaged terminals.
- Test continuity: Disconnect at least one wire from the bake element and measure resistance with a multimeter. A typical element reads 15–40 Ω. If open (infinite resistance), replace the bake element.
- Control board check: If the element tests good and wiring is intact, the bake relay on the control board may be faulty. This requires board replacement, best done by a qualified technician.
- Reassemble and test: Reinstall panels, restore power, and test a bake cycle. If E03 persists with a known-good element, schedule professional service.
