Motor out of sync

Posted by earlybird_2007 (My Page) on

My 1/2 HP Craftsman GDO-13953629 SRT recently raised too high and jammed against the stop bolt on the track. The motor will only run in one direction-up. I tried removing the chain but it would not run down. Is there an easy way to get the motor back in sync? I would really appreciate any help I can get on this.

Thanks,

jimbo

Sounds like your up and down limit assembly may be broken or badly mis-adjusted. Take the cover off and you will see it right on the bottom. Check for broken parts. Have you adjusted anything?

Yes, I have probably got the limit switchs out of adjustment trying to get the motor to run the other direction. I don't see anything broken though. How do I set them correctly?

Thanks

First thing I would do it adjust the up limit until it is touching the center contact. At this point your door should go down. You can now adjust them to open and close the door the proper distance. Let us know what happens.
