Check to make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them if necessary. If you can't get both lights to come on you have bad sensors.

My craftman garage opener will not close. The up arrow blinks 3 times and the down arrow blinks 2 times. the button on the unit will not open or close it. It will move about a foot then reverse back.


try holding in the wall button the whole time. if the door closes, then you have an issue with the sensor wiring. if the wall button closes the door while holding in, then post a comment below and we will tell you next steps.

I have a model 139.53672srt1 garage door opener.Door opened fine but will not close from remote or wall switch, light goes on but door does not move or engage.


if you hold down the wall button will the door close? if yes, then the safety photo sensors are the issue==pretty common issue. either they are not aligned or one of the wires to then is lose or broken or shorted out(staples thru the insulation)

Have you checked the tracks on both sides? If the door closes when you hold the wall button there may be an obstruction or a bad guide. This could exert enough resistance to make it stop and reverse. Holding the wall button allows it to keep going past the problem.

Green light flashing and opener button does not work


It sounds like your wall control is bad. Remove it from the wall and then remove the two wires on the back. Remember which wire goes where as they are color coded.

Must hold wall unit to close garage door...


there is an error in the system. most likely The safety beams (mounted on the track near the floor) are out of alignment and the LED light should be blinking. The garage door opener will not let the door close if the beams are misaligned. Realign them and the LEDs on the beam or on the operator will stay on. you should be able close the door now with one push.

Garrage door opener ability to close the garrage door


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?

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.

Garage door opener


it works but it is annoying: you will have to hold down the button on wired wall unit. hold it until the door closes. also if you have the keypad outside it also works the same way, type code and hold the enter button

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

My garage door opener will open the door but will not close it. i have to close the door with the manual button on garage wall.


when you close by wall button, are you pushing it or holding it. if holding, you have a safety beam problem.
