Sounds like your drive gear may be going bad. Remove the cover from the motor unit. It will be obvious if the gear is bad. Also check to make sure the sensors in the doorway are pointed at one another.

It is sears/craftsman K1026 139.53779 HBW 0709 . Button on the wall inside the garage will open, but does not close . it starts vibrating and the motor light flickering and no advancing. Only if you hold...


If the main light is flashing 10 times when you try to close the door it is a door sensor problem. Make sure the small light on each one is lit, not flickering and that one is not dimmer than the other. Tweak them a bit if necessary.

Garage door only closes halfway


If the main light is flashing 10 times when the door reverses when closing it is a door sensor problem. You can override this with the door control but not with a remote. Make sure the door sensors are pointed at one another and the small light on each one is on and not flickering.

Have to hold the push button inside my garage to close garage.


You have a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not blinking. Also check the wiring.

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.

The garage door works when it wants to.


You have a problem with the safety eyes. Make sure a light is on on both eyes. If not, realign until both lights come on.

Automatic garage door


Hello,

There should be 2 sensors on the bottom of your door on the inside, 1 on the right side and 1 on the left side.
These sensors serve 1 purpose to send a beam or reflection to each other.
If something is blocking this reflection or is in front of the sensor the door will always come back up.
It is a safety feature so nothing or no one gets hurt when the door is closing!

If the door closes by holding the wall button you have a photo eye issue. Check your photo eyes for proper operation.
