My Craftsman garage door will not close, only a few inches at a time


have a problem which returns every year when outdoor temperatures drop close to freezing. garage door will open only a few inches, then stops. I can close it and try opening it again... same result. After five or six such attempts it typically will open. Interestingly, when I push the switch button mounted on the interior wall of my garage and keep it pushed, the door will open, until I release the button at which point it stops opening.

My Craftsman 1/2 hp garage door opener does up about 4 inches and stops. When I press the opener again it goes down and reopens all the way. What is wrong with it?


Check your door springs to make sure you don't have a broken spring. Remove the cover from the opener motor unit and check the drive gear. It is a white nylon gear just in front of the motor. It will be obvious if this is going bad. On the rear of the motor unit you will find the 'up force' control. Increase this just a bit. This will compensate for door springs getting tired.

My 1/2 hp sears craftsman garage door opener bought in 1992 has stopped working, The motor hums when the remote or wall button is pressed but the door will not move at all. Please help


Most common cause of the problem you describe is a bad start capacitor. Remove the cover from the motor unit. The capacitor is about 5 inches long and 2 inches in diameter.

Craftsman garage door does not open all the way stops @12 inches


You most likely have a broken door spring. Release the door from the opener and try lifting it by hand. Look above the door for the springs.

Programming kepad for Sears Craftsman Garagedoor opener 1/2 hp


The only procedure I have ever followed is to press the learn button and then enter the code, and not do anything else. I think your last step of holding the button until the light goes out is clearing codes as fast as you enter them. Just stop after you enter your code and let the learn mode time out on its own. That should do it.

And don't put your head through the wall. It just causes more headaches.

Garage door will open to sensor level and stop


You might have a broken spring. Check on the a the header above the door there should be a tude with a drum on each end and 2 springs (maybe one) towards the center. se if one of the springs has a gap (1-2 inches) in it. If it does you will nedd to cal a door company in your area. I recommend you replace both springs.
If you need to get you cars out some times you can help the operator to lift the door by lifting the door while the operator is lifting the door. Be very careful not to get your fingers in a pinch point and be sure to lower the door the same way.

Door opens only 6 inches and stuck


I would try jumping a wire across the white & red terminal to see if your safety sensors are working Properly! If your door opens you have a loose connection or faulty sensors.
