How to Fix / Troubleshooting
Safety first: If you see flames or heavy smoke, turn off the appliance and, if safe, disconnect power and close gas.
Steps:
- Inspect the oven cavity for heavy grease or food residue; perform a thorough manual cleaning with appropriate oven cleaner (avoid spraying directly on sensors or elements).
- Remove cooktop grates and burner caps; clean spills and debris from the surface and burner bases.
- If the smell is electrical (sharp, acrid), disconnect power and inspect wiring behind the control panel and at the terminal block for signs of overheating.
Replace any burnt wiring or components. Persistent electrical smell requires professional diagnosis.
