How to Fix / Troubleshooting

Safety first: If you suspect electrical burning, turn off the breaker immediately and do not use the oven until inspected.

  • New oven smell: For a new unit, some odor is normal during initial use. Run an empty bake cycle at high temperature with good ventilation to burn off residues.
  • Inspect elements and cavity: Once cool and power is off, check for plastic, packaging, or utensils touching the elements.
  • Check wiring: Remove the rear panel and inspect wires to the bake and broil elements, terminal block, and EOC for melted insulation or discoloration. Repair or replace damaged wiring.
  • Inspect control board: Look for burnt components or darkened areas on the EOC. Replace the electronic oven control if damaged.

When to call a technician: Any confirmed electrical burning smell should be evaluated by a professional before further use.
