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.

Door sensors have nothing to do with door opening. Only closing. It sounds like you have a bad gear in the motor unit. Remove the cover and it will be obvious if the gear is bad.

I have a sears craftsman garage door opener 139.18805 1/2 HP or 139.18850 the machine is about 6 years old and it has just started to act up. It will open only part way about 4 ft then I can close it then...


Take a close look at your door springs. Could be a broken one. If not, remove the cover and look at the drive gear. It is a white nylon gear just in front of the motor. May be going bad. It will be obvious if it is. Release the door from the opener and try opening it by hand. If it is heavy you have a spring problem.

Garage door will not open manually or automatically/normally


The color of the sensors is normal and have nothing to do with your problem. If you cannot raise the door manually and it is released from the opener then you have a door problem. If you mean the door won't open and you cannot get into the garage to release the opener then you are going to have to call a door technician for help. He will get in.

Door won't close, blinks 10 times, sensor light yellow


Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem or the wiring to them. Nothing else causes this symptom.

Left Sensor has yellow led & right sensor is green. Garage closes and then immediately opens. I'm assuming it's the sensor with the yellow led. How do I fix this?


If the main light flashes 10 times when the door reverses it is a sensor problem. Make sure the door isn't hitting the floor and then reversing. This problem will not cause the light to flash 10 times and can be corrected by adjusting the 'down limit' which is on the side of the motor unit.

Door opener moves foward about 10 inches then returns


UNPLUG THE UNIT FOR ABOUT 5 MIN. TO RESET TRY TO OPERATE IF IT STILL MOVES 6-8 INCHES AND FLASHES 5 TIMES THE RPM SENSOR IS YOUR PROBLEM - COULD JUST BE THE CUP HAS MOVED ON THE SHAFT. IF IT IS IN PLACE AND STILL NOT WORKING REPLACE THE PICKUP.

Door will only close when held down


That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.
