I am having a problem I hope someone can help me with. I just replaced the plastic gears in my Craftsman 1/2 HP garage door opener, and now the motor wants to turn one way for about 2 seconds, stop, turn the other way for about 2 more seconds, then stop completely. This even occurs when the garage door is NOT attached to the garage opener.
Is there a reset button that I can't find on this unit? I've taken the load off the motor, checked all stop contacts (which are all open - not the problem). What might be wrong? I've called Sears, but to no avail. Responses can be either to newsgroup or email. Thanks in advance.
Regards,
Tim
