Probably a broken wire to one of the sensors. Holding down the wall button overrides the sensors.

If you move the wires at the back of the power unit and at the sensors watch for the sensor lights to flicker. - If they do the wires you just moved are the problem.

If moving the wires doesn't help you will need to trace the wires & watch for a broken wire loose connection etc.

Hope this helps

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

Make sure the brackets for the sensors are tight and the small light on the sensors is not blinking ever so slightly. You also might try shading the sensor so that the sun is not shining directly into the lens.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

Need wiring diagram for eyes that control safty device door willnot close by one button push , have to hold button to close , light on opperator has one flash


Safety reversing sensors wire open (broken or disconnected).

Each sensor has a solid white wire and a white wire with black tracer.

The solid white wires go to terminal 2 and the wires with the black tracer go to terminal 3.

Sears garage door opener 1/2 hp about 6 years old. Will not respond to remotes to open and close. Light flashes on opener when remote is pressed but no door action.


Door sensors are not working. Check if lights are on both sides.
Might be misaligned or one is bad.
Door will close if you hold in the garge close button until it's all the way down.
And it will open on it's own.
You can get these off ebay.

Garage door won't close w/o holding down push button on wall


Check the door sensors. They must be properly aligned to work. Both of them has a small light that must be lit and will only light when they are pointed at one another.

your infrared sensor is either misaligned, faulty, or you have a broken wire from your sensor to your door opener. (Flashing light indicates infrared light path is broken). both sensors should indicate green led. door wil not come down is safty feature to prevent door from closing when light path is broken.
