Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

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 close but will reverse after about a foot. I checked both the photo eyes on the door and both seem aligned and both have the proper lights showing. Wiring also seems to be good as I have checked all connections and for broken wires. Presently the only way to close the door is to hold down the inside wall switch until it is fully closed. Tom Goodrum 1-2-13

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.

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: Garage Door Wont Close Craftsman 1/2 HP (1998)

What it is is the electric beams at the door are getting blinded buy the sun or out of line. They are the two black boxes on both sides of the door about a foot from the ground. Put a piece of card board in front of them not blocking the beam dut to block the sun. All that they are is safety beams for kids so they do not get hurt. If you have to move them to the top where the sun will not hit them. Sorry to say though you can not remove them all the way. Also make sure the lite on them is not blinking if so they are out of line.

Good Luck and Please Rate FixYa!

SOURCE: garage door won't close by remote in cold weather

There are ususally two adjustments on garage door openers...
One is for the pressure and the other is for the travel. Assuming that the travel adjustment is properly adjusted...

On a cold day things are a little tighter and it "wants" a little more downwards pressure to complete its cycle. Sorta like me in the morning -- I need a little coffee to get going on a cold morning.

Adjust the down pressure/force just enough to make the unit close properly. Do not over adjust the down pressure or you will find it won't stay closed. Sometimes the manufacturer doesn't make it too clear where this adjustment is, but you should be able to find it if you look around.

I have seen units that were installed for years all of a sudden need a little tweak of this adjustment.

Good luck

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.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

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.

Garage door opener closes when closed


Try this: Loosen the chain enough that you can remove it from the sprocket above the motor. Now run the opener until the sprocket turns in the clockwise direction and stops. Reconnect the chain. This will get everything in sync and you will have to tweak the 'up and down limits' a bit to get it just right.
