Description

This door/interlock switch completes the electrical circuit when the appliance door is closed, allowing the unit to start and run. Replacing a faulty switch restores reliable door detection and normal operation. What it does:

• Detects door closure and enables the appliance to power on
• Prevents operation when the door is open for user safety
• Stops intermittent starts or control lockouts caused by a bad switch
• Helps eliminate symptoms like no-start, no power to controls, or cycle interruptions

What's included:

• One replacement door/interlock switch

Install notes:

• Disconnect power (unplug appliance or shut off breaker) before installing
• Access typically requires removing the control panel or door inner panel; follow your model's service sheet
• Verify connectors and actuator alignment before reassembly
