Function & Importance

The microwave light switch board controls the interior lighting and plays a critical role in the door interlock system. When installed correctly, it ensures that the microwave light turns on automatically when the door is opened, and turns off safely during operation. This part also helps maintain proper microwave safety by ensuring the appliance only operates when the door is securely closed. A malfunctioning switch board can cause lights not to work, door interlocks to fail, or the microwave to stop functioning entirely.

Symptoms That Indicate Replacement

You should consider replacing the WPW10403040 Light Switch Board if your microwave exhibits:

• Interior light fails to turn on when the door opens

• Microwave does not start or stops unexpectedly

• Door switch feels loose, stuck, or unresponsive

• Flickering or intermittent light inside the microwave

• Microwave operates inconsistently due to faulty door interlock

Replacing the switch board resolves these common issues, restoring proper microwave operation and safety.
