THE SENSORS ARE A MUST THE SYSTEM IS DESIGNED NOT TO FUNCTION WITHOUT THEM.
SOUNDS LIKE IT IS TRYING TO CLOSE TOO FAR CHECK THE DOWN TRAVEL LIMIT ADJUSTMENT.

Make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor or bad wiring to them.

Wall mount button LED is flashing, remotes won't work, door won't close unless the wall mount button is held down until the door is fully closed


Sounds like you have a couple problems. First of all press and hold the button on the wall control that has a lock icon for 3 seconds and release. This should take care of the flashing LED and the remotes will now work. Having to hold the button on the wall control until the door is closed is usually a problem with the door sensors. Make sure they are pointed at one another and the small light on each is lit and not flickering.

IF ALL ELSE FAILS GET SOME DOORBELL WIRE AND BYPASS THE EXISTING WIRES AS A TEST - BE SURE TO CHECK THE POLARITY & LOOSE CONNECTIONS.

The door reverses back to open position instead of closing


SOUNDS LIKE A SENSITIVITY ISSUE UNHOOK THE DOOR AND TRY IT MANUALLY TO BE SURE IT DOESN'T BIND OR IS TOO HARD TO OPEN OR CLOSE.

IF ALL IS WELL CHECK THE SENSITIVITY SETTINGS ON THE BACK OR SIDE OF THE OPENER.

YOU WANT THIS SET AS LOW AS POSSIBLE AND STILL OPERATE THE DOOR WITHOUT REVERSING.

NOTE: THE FULL RANGE OF ADJUSTMENT IS ONLY ABOUT 3/4 TURN SO MAKE A VERY SLIGHT ADJUSTMENT AND THEN TRY IT AGAIN.

HOPE THIS HELPS

Pressing remotes the door won't go u[


It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

My garage door will not stay down when I try to close it.


IF THE DOOR CLOSES ALL THE WAY WHEN HOLDING DOWN THE WALL BUTTON AND REVERSES 6" FROM THE FLOOR WHEN NOT HOLDING THE BUTTON.
I WOULD GUESS THAT THE SAFETY EYES ARE MOUNTED ON THE TRACK.
WHEN THE DOOR CLOSES THE TRACK AT THE BOTTOM IS TOO TIGHT CAUSING IT TO FLEX AS THE DOOR GETS NEAR THE BOTTOM. WHEN THE TRACK FLEXES THE EYES ARE POINTING FURTHER AWAY FROM THE DOOR AND EVENTUALLY THEY ARE TOO FAR OUT OF ALINMENT AND THE LED WILL GO OFF - THE DOOR GOES BACK UP.

SOLUTION: YOU CAN USE THE CLAW END OF A HAMMER TO TAP THE TRACK OUT A LITTLE WIDER - TAP NEXT TO THE WALL ON THE BRACKET THAT HOLDS THE TRACK TO THE WALL. MOVE THEM ABOUT 1/4" EACH SIDE.

OR

YOU CAN MOUNT THE BRACKETS TO THE WALL OR THE FLOOR.

THIS SHOULD SOLVE IT

HAVE A GREAT DAY
