SOURCE: Garage door opener doesnt close the garage

If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light

SOURCE: My garage door opener won't close the garage door.

Most likely your door sensors have been bumped and are not aligned properly. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

SOURCE: Remote Control closes garage door but does not open

It sounds like a case of your keypad losing signal strength enough that it cannot transmit through the closed door. If a new battery doesn't do the job a new keypad will.

Chamberlain 1/2 HP garage opener main part 41A5389-1 will not close door. Motor stops about 1 ft into travel on screw. Nothing blocking door - can easily open and close door manually. What to do?


If the main light flashes 10 times you have a door sensor problem. Make sure the small light on each sensor is on and not flashing. Tweak them if necessary. If the main light does not flash then you can try increasing the down force just a bit. This is a control on the side of the motor unit where the small gray antenna hangs. If this doesn't work you probably have a bad IR sensor which is a small printed circuit board just in front of the motor.

Garage door will not close, moves 2 ft & returns


Make sure you put the black cup back onthe end of the motor shaft and that it is pressed all the way on.Make sure the RPM sensor is plugged in. If neither of these are theissue, then you probably did not have the motor shaft pushed all theway back when you tightened the coupler after replacing the wormgear. Loosen that coupler up and from the front of the motor(opposite end in which the coupler is on) push the shaft back as faras it will go. Hold it there while you tighten the coupler back upand then try it.

Door opens up for 2 ft then slowly closes down


Sounds like one of your door springs has broken or the drive gear is going bad. The gear is white nylon and is just in front of the motor.

You may not have had the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear.

I just replaced the gears in the opener and now the door stays open about 2 ft. When I hit the button it closes about 1 ft. and returns to it's original position...


Loosen and then remove the chain from the sprocket above the motor. Run the opener until the sprocket has turned in the counterclockwise and stopped. Now with the door in the open position replace the chain on the sprocket and tighten. This will get you close and minor adjustments to the up and down limits may be needed.

How to switch back to automatic after manually close the garage d


mikey-moore's advice helped me figure out what to do but it's not exactly what I had to do. Manually open the garage door all the way. Then hit the automatic button you normally would use to open and close your garage door. The bracket slides back and locks into place. Hit the automatic button again and the garage door should automatically close.

Chamberline 1/2 hp belt drive opener that stops opening


It sure sounds like a broken spring. Sometimes the break can be difficult to see. How heavy is the door to lift manually. This will give you a good idea.
