Possible Causes
Open-circuit grill element, Burnt grill element terminals, Faulty grill relay on control board, Damaged wiring to grill element from heat
How to Fix / Troubleshooting
Safety first: Turn off power at the mains and allow the grill area to cool completely.
- 1. Visual inspection: Remove the grill pan and shelf. Inspect the grill element for sagging, cracks, or burn spots. Any visible damage means the element should be replaced.
- 2. Access connections: On many Rangemaster ovens, the grill element terminals are accessible from the rear or top once the panel is removed. Check for loose or charred connectors.
- 3. Test the grill element: Disconnect the wires and measure resistance. A typical grill element will read between 15–40 Ω. An open circuit indicates failure.
- 4. Check wiring: Inspect the wiring from the element back to the control board or selector switch. Replace any overheated or brittle wires and ensure secure crimp connections.
- 5. Control relay or selector: If the element and wiring are sound, the grill relay on the control board or the mechanical selector switch (on some models) may be faulty. These components usually require replacement rather than repair.
Tip: When replacing the grill element, support it properly to avoid bending and ensure all mounting screws are refitted to prevent vibration and premature failure.
