You have a bad logic board. Cost is about $80.00 for the part.

    It is common to have an electrical surge along with an outage. This can cause the type problem you are having.

Garage door will not close unless you hold inside button down


It could mean that there is something in the way of the electric eye or that they are misaligned. They are about 18" up on either side of the garage door. Check for interference or they may have been bumped and need alignment

Two things. Check for a broken door spring. If okay, remove the cover from the motor housing and check for a bad drive gear. This is a white nylon gear just in front of the motor. If it is going bad it should be obvious.

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

It could be closing too far or the sensitivity could be set too sensitive.

Lube the springs, wd-40 rust may be the whole problem.

If the door hits and the opener continues to move until the rail flexes upward and then reverses - probably the travel adjustment.

Does the door close and stay closed if you hold the wall button down constant until it closes? - this would indicate a safety eye problem.

If the door reverses before it hits the floor or just as it hits the floor it could be the sensitivity or if the safety eyes are mounted to the track they could be flexing enough to move the eyes out of alignment.

Hope this helps.

your garage door has saftey sensors at the door
these are photo eyes
in the owners manuel that came with the opener
that has pictures in it which would help
the photo eyes need to be clear of debri and aimed at each other with no obstruction
there are leds on each sensor and when aimes properly they should be light if i remember correctly
if you can not get them to light then you may have to replace the sensors

Myt 1/2 hp craftsmand door opener clicks and light


If the main light flashes 10 times when the door reverses it is a door sensor problem. Each sensor has a small light that needs to be lit and not flickering for them to work. They must be pointed at one another for the lights to be on. Tweak them a bit and see if the lights come on. If not you likely have a bad sensor.

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.

Sears craftsman garage door opener


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?
