Tips
- Always check the simple things first: is the timer on? Does the light activate when the door is opened?
- A bad door switch often lacks an audible click and doesn't snap back into place.
- Carefully remove and save all screws during disassembly.
- Be cautious when removing screws near the blower housing; they can easily fall into the unit.
- Use a small screwdriver to release stubborn wire harnesses.
