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

1 Answer

My garage door opener doesnt close all the way.

I hit the wall switch and the remote and I get the same result, the door goes down about 3 feet, stops, then reserves itself. The lights on the opener do not blink, it just stops. My garage door opener is a chamberlain liftmaster professional formula 1 opener.

The motor is probably either stalling because the door is too stiff, or you have a beam break detector that is being triggered when the door is halfway down.

Went to my garage to get items out of freezer and my garage door opener was down, no one handle the remote, or push any buttons at all, went back to the garage to get bottle water and the door was wide...




Anytime a door opens and/or closes randomly or doesn't work consistently I look for a smashed wire between the motor unit and the wall button.


If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.


Loosen the staples with a small screwdriver and slide the wire about ?½ inch to move any areas of thin insulation away from the staples.


The second thing would be a bad wall button or a remote with a sticking button.

Or a remote in someone

Garage door won't open or close using remote (light on lifter flashes twice) but will open and close using the button inside the garage.



WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

Garage door goes up but will not go down.

Remote does not open or close garage door; inside button flashes


What has happened is that you electric eyes are blocked or have gone out. The eyes are at the garage door about a foot of the ground on both sides. There should be a red or green light on one of them. If not some thing is blocking the beam that goes across the door. It is a safety beam so kids can nt get hurt when the door is coming down. If the beam is broke the door will go back up.

The garage door works when it wants to.


You have a problem with the safety eyes. Make sure a light is on on both eyes. If not, realign until both lights come on.

Check to see if the Vacation switch is locked on your wall console. It is a switch on the top of the black wall button. If that is not the problem it sounds like you need to program your remotes. Drop down the plastic cover towards the back of the unit There is a learn button push that and a red LED will come start flashing press and hold the button on your remote until the LED stops flashing (solid red) press the button on your remote again and the light will go off. This will program a remote

If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light
