1/2 Craftsman opener only closes a few inches and then opens
The garage wouldnt go up yesterday and when I took the cover off I relized the drive gear had been stripped down and not making contact. However, the motor itself was still going through its cycles. I replaced both the worm and drive gear and thought my project was over. However, now the opener will only run the down cycle for a few seconds and then stops and goes back to the up cycle for a couple of seconds. I thought it might have been a part I put in so I stripped the opener down to nothing except the motor and the motor runs the same way without anything else hooked up to it. Therefore, I am thinking my problem may now be the motor. Please give any advise thay you may have. Thanks.
