Possible Causes
Failed convection heating element (ring element), Loose element connections, Damaged wiring to convection element, Faulty convection relay on control board
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the oven to cool.
- Access ring element: Remove the rear panel inside the oven cavity to expose the circular convection element around the fan.
- Visual inspection: Look for cracks, burn marks, or breaks in the ring element.
- Continuity test: Disconnect one wire and measure resistance. Expect 20–40 Ω. If open, replace the convection element.
- Check terminals and wiring: Ensure all spade terminals are tight and wiring is not heat-damaged.
- Control board: If the element and wiring are good, the convection heater relay on the main board may be defective and require replacement.
