Sounds like a loose connection inside the unit. When you move the light fixture on the motor and get it to light, the contact is reestablished, possibly being a loose wire. With the vibration from the operation of the opener, the connection will lose its contact again and the motor ceases to function. Have an electrician give it a look or disable it's power so that you can remove the cover(s) and investigate yourself.

On the sensor for the craftman garage door opener 1 is orange and the other is green and my garage door doesn't open with the remotes


Nothing wrong with the sensors. They don't work when the door is opening anyway. Only when closing. Make sure the light in the wall control is not flashing. If it is press and hold the lock button for 3 seconds.

My garage door is a craftman . The problem is the door opens fine but won't close unless u hold the button till its completely closed. I noticed this only happens when its cold out any suggestions !!!


If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit.

Craftman garage door opener closes via the key pad and immediately reverses and reopens. have adjusted travel limit as well as force. Any suggestions


If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors or the wiring to them.

I have a craftman garage door opener. I cannot close with remote. Please help me


If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure they are pointed at one another and nothing is blocking them. Each one has a small light that will be one when they are pointed correctly. If you can't get both lights to come on you need new sensors.

Garage Door Opener Lights


Some craftman operator don't have that feature. Are both photo eye lights green? Feature not available. If the photo eyes are yellow and green feature should be avilable. The operator needs to have a three button wall station. With the light on the operator off press and hold the "light" button for about a minute until the light flashes.

Garage door won't close


your door travel screw is set to go too far on the downward travel. you need to set the down travel. It is set to go too far down. find the screw adjustment on the unit that says close and back off the screw a full turn until door stops short of floor. then start turning screw other way until door just touvhes floor.
