SOURCE: Door will only close when held down

That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.

SOURCE: Chamberlain Liftmaster Pro. Garage door Problems closing

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

The door wont work with the remote. it will only work by using the pad that is mounted in the garage.


Make sure the small light in the wall control is not blinking. If so press and hold the lock button on the wall control for 3 seconds. This will stop the blinking and your remotes will work.

The hand held divice stopped working and the mounted pad light flashes quickly. The mounted pad does work.


The most likely problem here is that your wall control is bad. I would disconnect the 2 wires going to it and I think you will find your remote works. Replace the wall control.

If the wall button will operate the door up but none of the devices do then look at the wall button. Find the lock button and push it for 2 seconds and then try the remotes again. This is your vacation lock. You can get a manual at chamberlain.com. Now if the door does not open or close with the remotes you can reprogram them. Press the colored learn button on the motor head and then press the button on the remote. Repeat for each remote. If they fail to program you will need a new logic board. Thanks BB

It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.

This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck

Garage Door Key Pad


Assuming, from what I read, the remote works..The inside switch is just a doorbell switch which will wear out or have the contacts get bent or dirty. Take off wall, and change for new one or see if the contacts can be cleaned or adjusted. If the pad is electronic (coded) the wires may be bad or the control defective. Usually momentary contact of the two wires will cause the door to actuate.
