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

1 Answer

My fixed garage door opener opens fine, but only closes if it is held down. My remote garage door openers do not work at all. I replaced the sensors and they appear to work fine. I tried to reprogram the remote controls, but they were not responsive.

If the sensor is working right, that leaves the downward force sensor tripping. First check for track obstrucions by manually moving the door with the lift disengaged. If door works without excessive force, then increase the force sensor of the lift a bit.

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.

Sears garage door opener 1/2 hp about 6 years old. Will not respond to remotes to open and close. Light flashes on opener when remote is pressed but no door action.


Door sensors are not working. Check if lights are on both sides.
Might be misaligned or one is bad.
Door will close if you hold in the garge close button until it's all the way down.
And it will open on it's own.
You can get these off ebay.

You might possibly have held the smart/learn button in too long and erased the code for the remote. Hold the button down on the remote and then press and immediately release the smart/learn button. This should program it for the remote. Now make sure the keypad is still working.

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.

I have 2 liftmaster 3245. The hand held remotes were working fine then stopped. I replaced the batteries and turned of all electrical/RIF close by. Still not working. Both cars operate the doors with no...


You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

Garage door will not close


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.

sounds like the safety door sensors are at fault,also did you reprogram the remotes by pressing the smart button on the logic board,when the safety sensors are bad the door will reverse to open state.you can pully the rip cord to manualy close the door untill you solve the problem.
