I have a Genie Screw Drive opener, and it just started not working. The opener sounds like it is running, but the screw drive will not turn with door engaged, but does turn when door releaed. Any ideas for fix or cause will be greatly appreciated.
Unplug it and remove the metal cover. Most likly the plastic gear is striped.
Unlock the door by pulling down on the rope hand and try opening up the door. It should be able to lifted with one hand farly easy.
