Bathroom vent cover stuck in up position...

When I toggle button up or down it makes the usual "Rrrrrrrr" sound but the vent cover doesn't move. Any ideas what's broken and needs replacing?

thanks!

Was that suggested by a fellow RVer that you had a screw loose?

Problem solved. There was a screw loose on the underside of the lift mechanism causing the gear to drop. Tightened that up and it works normally again. When I removed the screen from the inside the gear dropped down on top of it. Looked normal from above (the roof) though.
