sears garage door opener

dry-cleanerNovember 30, 2010

I replaced the gear assembly and after turning on power activated motor. It only went a short time clockwise before reversing. When attached the door opens but only moves a few feet when activated to close .

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.
