Model Mt5011 Operator Quit Working.

I opened the door using the remote, but stopped it with the wall mounted contacts. When I went to close the door, it wouldn't respond with either the remote or wall contacts. There's 115V power at the unit, but there's no noise from the operator when I attempt to open or close the door.
