Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener

Door operators when it is disconnected

When the door is connected it goes up about 8" and stops

  • Anonymous Dec 21, 2008

    I have the same problem in the cold weather, usually below -10 with out the sun. I have found that If I disconnect the opener from the door , close the door manually then activate the opener to the closed position, it will stay closed. I believe this has more to do with the door resistance (since it is cold) than the opener as the opener is only doing what it is designed to do and sense the resistence. You may find adjusting the door opener sensitivity in cold weather will correct the problem - wcc

You might have a broken spring. Check on the a the header above the door there should be a tude with a drum on each end and 2 springs (maybe one) towards the center. If one of the springs has a gap (1-2 inches) in it. If it does you will need to call a door company in your area. I recommend you replace both springs. If you need to get you cars out some times you can help the operator to lift the door by lifting the door while the operator is lifting the door. Be very careful not to get your fingers in a pinch point and be sure to lower the door the same way.

The garage door goes up one foot and stops..its a liftmaster professional half horsepower


Disconnect the opener from the door. Operate the opener. It should go back and forth smoothly.
Lift the door. It should go up and down without any problems.
After checking those things, there is a "up force" and "down force" adjustment on the opener, try increasing the "up force" by turning the adjustment in the direction of MORE force.

Every time I push the opener button the chain goes about an inch and stops abruptly. The door is not able to be opened or closed as a result. Is this an adjustment problem?


Disconnect the opener from the door.
Lift the door and ensure that it moves freely from fully open to fully closed.
Try to operate the opener. Does it go all the way from open to cloosed?
If the door operates smoothly and the opener works without the door connected, check the up/down force adjustment on the body of the opener.

My liftmaster garage door only opens 8 inches and then stops


It sounds like the opener is stopping because the weight of the door is tripping the lift sensor on the opener. There are two screws on the side of the opener to adjust the lift and close pressure. Find the lift pressure screw and ajust it higher to see if that remedies the problem.
Also, because you said the door will not stay open at the top when you open it manually, I think your springs are not adjusted correctly. They should hold the door open in the up position when not connected to the door opener. That may be the reason the opener lift pressure is kicking it out.
If you have to adjust the springs, be careful that you know what you are doing. There is a lot of potential for getting hurt if you don't know the proper proceedure.
Good luck.

Garage door goes up, but only travels about 12 inches and stops when it comes down


TRY HOLDING DOWN THE WALL BUTTON TO CLOSE THE DOOR.
IF IT WORKS THE PROBLEM IS IN THE SAFETY EYES.

IF THE DOOR TRUELY GOES A FOOT OR MORE AND THE ABOVE DOES NOT WORK - DISCONNECT THE DOOR FROM THE OPENER AND MAKE SURE IT WORKS SMOOTHLY - LUBE THE SPRING(S) ETC,
IF IT GOES UP AND DOWN WITHOUT TOO MUCH EFFORT ADJUST THE DOWN SENSITIVITY - NOTE: THIS IS A VERY SMALL ADJUSTMENT 1/8 TURN IS MORE THAN ENOUGH
