    Every winter my garage door opener will close then automatically go back up. There are also times when it will not go down at all and I have to hit the the wall unit several times before it will move. I have done all the lubing as recommended. I have even tried the weight adjustments but to no avail.

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.

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.

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.

My Sears Craftman garage door opener closes about 1/3,stops,and reverses.When I activate the remote again it stops rising,starts down again, comes down another foot or so,stops,reverses etc.,etc,etc It...


If the main light is flashing 10 times when the door reverses it is a door sensor problem. One may have been bumped so that they no longer point at one another. Make sure the small light on each sensor is lit and not flickering. If this isn't the case you might need to increase the down force a little. The control is on the back panel near where all those white wires go. Increase it about 1/4 turn and try.

3.75 craftman garage door goes down a foot then immediately reverses back up


If when it does this your main light flashes 10 times it is the door sensors. Make sure they are aligned properly. If the main light doesn't flash 10 times then you most likely have a bad RPM sensor board. It is a small printed circuit board just in front of the motor.

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.
