    When I back off the down limit it doesn't close the door. It stops about an inch from closing. Thanks for answering though.

    You seem to have turned the down limit too far. Sometimes they are very sensitive. Also, your "j" arm (the arm that connets the operator to the door) should be almost vertical when the door is in the down position and the curve part of the "j" should be monted about 2" below the top support (strut) on the door.

My garage door wont open more than 6 inches with the door attached to the belt, but when I releasae the door load the belt works just fine. It worked fine for 6 months but now i have this problem....


YOU MAY HAVE A BROKEN SPRING

CHECK TO SEE HOW THE DOOR WORKS MANUALLY - DISCONNECTED FROM THE OPENER. IF YOU CAN'T LIFT IT EASILY THE SPRING MAY NEED TO BE ADJUSTED OR REPLACED.

IF IT LIFTS EASILY BY HAND THEN LUBE (WHITE LITHIUM OR WD-40) THE SPRINGS, HINGES AND OPENER RAIL - TRY IT AGAIN, IF IT STILL REVERSES ADJUST THE OPEN SENSITIVITY 1/8 TURN AT A TIME IF IT TAKES MORE THAN 3/4 OF THE ADJUSTMENT RANGE OR STILL DOESN'T WORK I WOULD HAVE IT LOOKED AT BY A PRO. SOME THINGS YOU CAN LOOK RIGHT AT AND NOT SEE.

HOPE THIS IS HELPFUL

Cant program unit. It only moves to close position, opens 2 inch


You are the only one for sure. Take the cover off the motor unit and watch how the limit switch assembly works. It is misadjusted.

Installed new PD432D opener from Home Depot. Inadvertently ran motor before connecting rail and screw drive. After connecting, I cannot get upper limit adjustment to bring rack all the way to full open...


You have to set the limit adjustments to the factory settings and then make sure the trolley placement is in the up position and install from there. You can't do this by simply adjusting the limits. This might be a case when you hire an installer. 100.00 dollars should do it, depending on the market. Thanks BB

You have a stripped gear inside the opener. When you take the cover off it will be full of small white flakes. Replace the entire gear and sprocket assembly
