Frequently Asked Questions
•How do I locate the door switch on my specific Roper dryer model?
The door switch is typically located near the dryer door opening, often on the dryer's cabinet frame. Consult your dryer's service manual or online parts diagrams to find its exact location.
•What voltage should I expect to see at the light fixture when the door is open?
You should expect to see approximately 120V AC at the light fixture when the door is open and the door switch is closed, completing the circuit.
•If the door switch tests good, what are the chances the MCU is actually the problem?
If the door switch tests good and the wiring is intact, the MCU is a likely culprit, but it's still a good idea to double check that you aren't overlooking something like a loose connection to the light fixture itself. MCU failures are less common than door switch issues, but they do happen.
