Microwave/Oven Combination Switch Summary:
The switch, identified as the Interlock Door Switch, is integral to LG appliances and certain Sears-Kenmore models. Its primary function is to ensure the microwave operates only when the door is securely closed. By communicating with the microwave's electronic control board, the switch verifies whether the door is open or closed, allowing or preventing operation accordingly.
Due to frequent use, the interlock door switch may experience wear over time.
Signs indicating a failing interlock door switch include:
- The microwave continues to operate or heat when the door is open.
- Error codes or door sensor warnings appear on the control board display.
- The microwave fails to start, even when the door is properly closed.
This LG component is also compatible with specific Sears/Kenmore microwave models.
