sears garage door opener intermittent problem
To: Don the Garage Guy
I have a very frustrating intermittent problem with my Sears Model 139.53924 2 year old screw drive opener. After a half dozen service calls from both Sears and independent garage door service people the problem comes back.
The unit intermittently opens about 6-8 inches and stops.Try several times and it may close and then it opens. The garage door opens manually with very little resistance and is properly balanced. Sears as told me the problem is in the door and the garage door specialists tell me there is nothing wrong with the door! Both the up/down force and limit adjustments have been tried to no avail. Sensors are clean and aligned. Spring and some hinges have been replaced. I suspect something is wrong with the logic board which Sears appears to have overlooked in their service calls. Is there some simple fix or is it possibly in the logic circuit? Don the Door Guy PLEASE advise!! Thanks.
