craftsman 1/2 hp garage door opener
I have just replaced the door opnere spindle, due to the teeth were srtipped due to frozen door.
After I replaced the spindle gear, the garage door would not operate. It would close, then come back up and the glide bar would lock up at the bolt in the rail. I pressed teh operation button and teh motor tried to start but did not operate and the green light on the back of the opener blinked green. I re-adjusted the chain tightness several times, with no avail. Is there another problem showing up?
