How do I repair the actuator door switch

Hello, you'll have to verify that first there is power to the actuator, and then verify the command to move it is coming through. Then, you have to make sure the "new" actuator works. Even new parts fail occasionally. Last, the actuator could be working fine, but I've seen fractured plastic in the plenum causing the door to not turn. So check this also.
