Check to see if sensors (eye) on sides of door are lined up, they need to be looking directly at each other. If that doesn't work change sensors, simple, install, hook up 2 wires per sensor, wire with line to same wire, blank wire to same blank wire and align so sensors see each other.

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.

Check the resistance down button (There is one for down and another one for up). You may need to adjust the sensitivity. That way even if for some reason the have hard time coming down, less sensitivity may solve that issue.

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.

Sensor problem with garage door opener. One of them has a yellow light the other a green. The door starts to close than stops. You can close it if you hold the button down inside and the remothe doesn't...


If it moves 6-8 inches and then stops it is most likely the rpm sensor.

Yellow and green are what the lights should be.

Does the led on the wall control blink?? If is does press the lock button.
If it doesn't you will need to reprogram the remote.

Watch the eyes as the door closes, does one of them go off? If so the track may be flexing causing misalignment. (Widen the track near the bottom)

If all of the above don't help check the sensitivity adjustment. Turn it about 1/8 turn clockwise and try the door again - continue this until the door goes full cycle without reversing. If you have to set the sensitivity past 3/4 the door needs to be adjusted.

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.

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.
