Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener
When remotes are keyed, the inside light on the garage door openner flashes a couple of time, but does not open the door.
The wall button on the inside has a lite in the button, normally it is on so you can see it in the dark; however, now it flashes continously. When you push this button the door moves a foot or so then goes back down; if you hold the button in, the door will go all the way up. Press and hold, and it will go all the way down.
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.

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

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 HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
