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

1 Answer

Not working My chamberlain garage door opener stop working, I press the button and it does not open or close, all it does is make this clicking noise and nothing is in the way of the sensors for the door to go up and down. I have a chamberlain lift master formula one model 2280r. It does nothing, I push the button and all it does is make a thump and then nothing. I have used this side of my garage maybe 10 times. There is also nothing blocking the sensors. one day it opened fine and would not shut again. The gears look brand new and the belt is not worn. I have not idea what to do?????

    Chamberlain told me to replace the logic board. I did, and nothing was fixed. Now I'm out $70 and nothing is solved.

IT MAY BE AGAINST THE TRAVEL LIMITER BOLT.

IF IT IS YOU WILL NEED TO UNPLUG THE UNIT REMOVE THE COVER AND TURN THE MOTOR BY HAND TO BACK OFF THE PRESSURE.

MAKE SURE YOU GO PAST THE LIMIT SWITCH.
ADJUST THE LIMIT SO TH DOOR DOES NOT HIT THE BOLT.

HOPE THIS HELPS

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.

I have a chamberlain whisper drive garage door opener. When I open the door and it reaches the top it starts making a loud noise. It's like the motor is still trying to pull the door up but it can't...


SOUNDS LIKE THE UP LIMIT IS EITHER OUT OF ADJUSTMENT OR NOT WORKING.

TURN IT ABOUT THREE TURNS COUNTER CLOCKWISE. THIS SHOULD BE ENOUGH TO MAKE IT NOT OPEN ALL THE WAY. THEN ADJUST IT 1/2 TURN AT A TIME THE OTHER WAY UNTIL IT GETS CLOSE THEN SMALLER ADJUSTMENTS TILL YOU ARE HAPPY WITH WHERE IT STOPS.

HOPE THIS HELPS

Chamberlain Lift Master Pro Formula 1 only makes click sound


Is the door stuck in the open position? If so the trolley is probably jammed against the bolt just in front of the motor unit. Loosen the chain enough to free the trolley and then run the opener until the door is closed. While the door is closed locate the 'up limit' on the side of the motor unit and turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

Liftmaster pro 1/2 hp wont shut in one button press


You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.
