Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Have a Sears Opener 76LE that has operated without trouble for over 25 years. Yesterday, I tried to open door and as soon as unit was under load, went into the close mode, then tried to open, then closed. Repeated this cycle until I unplugged unit and disengaged door. The motor, chain, belt, pulley and door all appear to be in good working order. I assume this is a control problem. Is this fixable and are parts available?

If your opener is truly 25 years old there are not going to be any parts available. The model number you give is not the model number. It starts with 139. and probably has 6 numbers after the period or dash. Once you have it you can go to Sears parts and see if there are parts available.

I have a Sears Crafstman Garage door wireless opener. Model 139.53615SR . The door hums but nothing happens. The chain doesn't move. The springs on the door broke last year and i replaced both of them....


My plastic gear stripped soon after a spring broke. I think the broken spring put a huge load on the opener that day and ruined the gear. Replacement wasn't too hard. It will be obvious when you remove the cover if the gear is stripped. Here are instructions:

Have your neighbor bring over his remote and open or close your door with it. Then hold the smart/learn button in for 6 seconds on your opener. Then see if he can open your door. He shouldn't be able to because that procedure erases the memory in your opener. No remotes should work. You need to get that remote #53778 back and program it and then see if your neighbor can open your door. If he can open your door at any point after you have held that button in for 6 seconds you need to get a new door opener.

I would remove the cover and take a good look at the limit switch assembly. If you watch it you will understand how it is supposed to work. There could be a bad connection on the logic board. You can remove it and check it over.

You can find a free manual for your door opener at manualsonline .com You might want to look at how to program it and change the unit to a different frequency. You can sometimes get better response and eliminate interference. Also make sure your battery contacts in the remote are clean.

Lift-Master garage door opener Model 1045-6 1/3 hp


Most residential garage door openers have a max. amount of cycles they can run per hour. Thus the difference between a residential opener which only needs to be opened a few times a day vs. a commercial opener which needs to open 10-20 times and hour. This could be your problem, you may be running too many cycles too soon. This would explain why it seems to work again after unplugging the power. You're resetting the unit. Hope this helps.
