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

1 Answer

The door only opens partially and then stops

The garage door only opens partially and then stops about a fifth of the way up. I have detatched the emergency rope from the bracket on the belt and manually opened and closed the door.

I re-attached the door to the drive belt again from the fully opened position and it closes perfectly but again only opened partially.

Any suggestions would be awesome. Thanks

My garage door opener does something different every time.Opens partially. Closes partially. Sometimes you have to push button multiple times for it to do anything. Who knows what it will do next.

this is likely a force setting issue, with all the humidity the door might be getting more stiff, on the back or side of the unit there should be a screw it adjust, or you can reference the manual, but before doing so you should release the door from the opener (handle on the trolley) and check to see just how stiff the door is, if the spring has broken you will have to get a door guy to fix it.

How do you stop the door leaving a foot open at the bottom?

To stop the door in a partially open position, the button on the wall switch or remote should be pulsed when the door is opening from the fully closed position.

Door closes but opens inmediatelly and partially,only 1 foot and a half

With the garage door up pull the release cord to disingage the garage door it self in the up position. You can skip the disengaging step, But,It saves ware and tear on the motor.

Then using a step stool you will find limit adjusting plastic slots/screws on the side of the opener.

The left screw is for garage door down.

I would turn the left screw clockwise 1/2 turn or less. then activate the remote opener. noting which way the latching mechanism moved. and so on.

It may take a few adjustments with this proceedure to get it perfectly closed. Then activate the remote to re-engage the garage door it self.

Also, LiftMaster has a web site that you can check out.

Check to make sure you don't have a broken door spring. Then remove the cover from the motor unit and check the drive gear. It is a white nylon gear and will be obvious if it is bad. If neither of these are the case you can increase the up force. The up force control is on the rear of the motor unit near where all those white wires go.

Check to make sure your door sensors are properly aligned. They each have a small light and both lights will be on if they are aligned.
