TRY THE DOOR MANUALLY AND RUN THE OPENER DISCONNECTED FROM THE DOOR(WITH DOOR IN CLOSED POSITION).

THIS SHOULD ISOLATE THE PROBLEM (ACTUAL DOOR PROBLEM OR OPERATOR PROBLEM).

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
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 OTHER?

IF THE DOOR STOPS/REVERSES (WITH DOOR CONNECTED) WHILE HOLDING DOWN THE WALL BUTTON TO CLOSE YOU NEED TO CHECK THE SENSITIVITY ADJUSTMENT.

HOPE THIS HELPS

Garage door will not stay down when closed


Sounds like the down limit is out of adjustment. Turn the Down limit switch opposite the direction of the arrow a quarter turn and try again. Repeat until the door stops before hitting the floor then fine tune to shut off at the floor.

It sounds like the door is traveling too far, hitting the floor and then reversing to the open position. If this is the case you need to locate the 'down limit' control on the side of the motor unit and turn it a bit in the opposite direction of the arrow printed on the cover. Some tweaking may be necessary to get it just right.

It is normal for that small green light to flash randomly. It can also assist in diagnosing some problems by flashing a code. It will flash a number of times and then pause and then repeat. If this is the case, post the number of flashes.

Garage door doesn't open and close properly


Loosen the chain enough so that you can remove it from the sprocket above the motor unit. With the door closed run the motor until the sprocket turns clockwise and stops. With everything attached replace and tighten the chain. Some adjusting of the up and down limits will probably be required.

After opening, my automatic garage door creeps back down a bit


There is a sensitivity switch for both directions, open and close. If you access the garage door opener in the ceiling, you will see two adjustment screws for calibrating these. I would highly recommend following the instructions in your manual, as these are life safety adjustments! Your sensitivity for closing the door is adjusted to the positive. You just need to back it off a little. Place a 2x4 on the floor of the garage where the door comes down. and when the door hits the 2x4, it should automatically come back up. If not, you adjusted it too far. Hope this helps. and remember, check the manual for your specific adjustment procedures.

Garage door won't close


your door travel screw is set to go too far on the downward travel. you need to set the down travel. It is set to go too far down. find the screw adjustment on the unit that says close and back off the screw a full turn until door stops short of floor. then start turning screw other way until door just touvhes floor.
