chraftsman garage door opener

couchcoachJanuary 27, 2010

My garage door opener stopped working and I found the gear was shot. I replaced the gear and now the door only moves 2 feet before it reverses. I do not get a flashing light and I was able to turn the motor freely with the trolly disconnected. I have tried the adjustments and no good. I can see the contacts that stop the motor when it goes up and down and those contacts dont make when the door stops. It looks like I may have an issue with the electronics. Any thoughts?

Make sure you put the black cup back on the end of the motor shaft and that it is pressed all the way on. Make sure the RPM sensor is plugged in. If neither of these are the issue, then you probably did not have the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear. Loosen that coupler up and from the front of the motor (opposite end in which the coupler is on) push the shaft back as far as it will go. Hold it there while you tighten the coupler back up and then try it.
