Open Question

Door closes only when wall switch is held down

Forgot door was manually locked and tried to open; now, the door opens ok but can only be closed from wall switch and then only when switch is held down, riding door all the way down (remote will open but not close door). Releasing the switch before fully closed causes door movement to stop and reverse direction.

sounds like the safety door sensors are at fault,also did you reprogram the remotes by pressing the smart button on the logic board,when the safety sensors are bad the door will reverse to open state.you can pully the rip cord to manualy close the door untill you solve the problem.

SOURCE: wall mount button LED is flashing, remotes won't

Sounds like you have a couple problems. First of all press and hold the button on the wall control that has a lock icon for 3 seconds and release. This should take care of the flashing LED and the remotes will now work. Having to hold the button on the wall control until the door is closed is usually a problem with the door sensors. Make sure they are pointed at one another and the small light on each is lit and not flickering.

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.

SOURCE: reversing sensor blinking

Tweak the sensors to see if you can stop the blinking. They must be pointed at one another and not blinking for them to work properly.

Why door wont open


There can be many reasons but lets try the most common one first.
No elect power supply to the motor - check circuit breaker supplying elect power to the control box and or DC transformer. Check DC power supply for transformer to control box.
If that is ok adjust the up load turn switch - normally there are two adjusters regulating the open and close forces applied by the motor. If set to sensitive the door will open or close partially or even not at all. Quick check is open the door by releasing the manual lock and lifting the door by hand. Lock the manual lock again, press the door close switch/remote and see if it will close. If it closes the up switch is set to sensitive. Adjust by turning not more than a quarter turn before trying opening the door. If not sure to what side it must be turned turn it fully to the left try - if not working fully to the right and try again. It is however necessary to reduce the setting to a point just enough to open the door with any manual/hand assistance but where it should stop moving if light resistance is encountered such as hand pressure against direction of travel.
Check the remote contol batteries.
Check for some obstacle in the way of the door.
Check if the door is not locked.
Lastly check the micro switch settings on the door motor.
If the problem is not solved manufacturer assistance support.

Have you checked the tracks on both sides? If the door closes when you hold the wall button there may be an obstruction or a bad guide. This could exert enough resistance to make it stop and reverse. Holding the wall button allows it to keep going past the problem.

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

Use the pull cord and disconnect the opener from the door.

Operate the opener and let the carrier slide back away from the door.

Is the carrier moving smoothly when disconnected?

Next, lift the door by hand from the bottom to the top. Is it moving smoothly?

If not, lubricate the axles of all the rollers on both sides of the door.

Check the cable pulleys at the top sides of the door channel, lubricate them as

well. Are all cables in all the pulleys, there are 4.

After checking those things, there is a "up force" and "down force"

adjustment on the opener, try increasing the "up force" by turning the

adjustment in the direction of MORE force.

Give me some thumbs up if this helps you.

All of a sudden our garage door stopped working and the light flashes 10 times. Liftmaster Model 2265 1/2HP. Any ideas?


We just had the same problem this morning (cold weather can mess these things up). Not sure what you mean by "not working". Ours would open part-way and then stop (or close part-way and then stop), but could open/close all the way if we held the button on the wall down the entire time it was lifting. After much research online, we ended up checking the sensors at the bottom of the garage door tracks to make sure that the green light was solid (not flashing). Ours flashed a bit, so we cleaned the "eye" and tightened it in place. Once the green was solid, we thought we were done, but still had the problem.

Then we began adjusting the screws on the unit itself that show pictures of the door opening and closing. We thought we were adjusting the torque in the unit (because we read online that cold weather can make it more difficult for the motor to work), but in reality we were adjusting the opening and closing "distance". Apparently cold weather can also do something to the tracks, which can require adjustments to be made. Something to do with ground swelling...

Anyway, we also discovered that when we had closed the door manually (red pull-cord) the night before for lack of a better solution, it never properly locked back into position, which was adding to the problem.

So, first, try cleaning the sensors. You need a solid green light for them to function properly. Second, if you have used the manual cord, make sure the arm that it attaches to is locked back into position. You can accomplish this by pulling the manual cord, manually closing the garage, and then pushing the button on the wall. The door arm should lock into place. Third, try using a screwdriver to adjust the open/close distance. Start with a 1/4 turn for each position, and play with it until you find the right setting.

If these suggestions don't address your problem, this link worked for us...http://forum.doityourself.com/doors-windows/368278-garage-door-wont-go-down-cold-weather.html

3/4hp craftsman will not close the door fully


There are adjustments on the unit itself that control the distance door travels to close as well as the force it uses to close. The info and location of controls is indicated in the manual that came with your unit.
