Check the door sensors. They must be pointed at one another and the small light on each one should be lit and not flickering. Tweak them a bit.

My Chamberlain 41A5389-1B 1/2HP door opener will only close via the wall push button when it is held down until door is fully closed. Will not close with remote, when using the remote it will start to...


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.

My liftmaster will open with the remote but to close the door, we have to hold down the wall unit. It starts to close, jerks to a stop, then we have to press and hole the button and it closes.


Hi, it is probably the safety photo beams out of alignment or not working, when this happens the garage opener goes into 'dead man' operating mode, ie you need to keep the button pressed for the door to operate.

My Liftmaster 1/2 H.P. opens but cannot be closed (without depressing the button on the wall until the garage door comes down all the way. Any help will be much appreciated


HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

Wall mount button LED is flashing, remotes won't work, door won't close unless the wall mount button is held down until the door is fully closed


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.

Liftmaster garage door openers Model # 3245 (remote Issue)


it is possible that when you programmed the car remotes you erased the pairing between your hand held remotes and the unit. Follow the instructions to pair the remotes again and you should be good to go.
