Door will only close when held down

Got the Chamberlain Professional garage door opener model 41BD002-2 & have to hold down button to close it until it goes all the way down. Tried moving sensor with orange light & it still won't change. Any other suggestions?

    I have the same issue. I am able to temporarily resolve it by slightly adjusting the sensors but the issue inevitably comes back - often the next time I try to close the garage.

    In my case yes - if I obstruct the sensor it will trip the light on the drive unit but the door still won't close unless I hold down the button.

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 garage door opener opens with remote but will not close with remote. will open with wall button but button must be held down until door touches floor to close


Check the door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.

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.

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?

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.
