!/2 hp craftsman garage opener is closed and when you push to open it tries to close.

That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.

Most likely your door sensors have been bumped and are not aligned properly. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

If the main light flashes 10 times when the door reverses it is a sensor problem. Make sure the door isn't hitting the floor and then reversing. This problem will not cause the light to flash 10 times and can be corrected by adjusting the 'down limit' which is on the side of the motor unit.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.
