Sounds like a bad logic board. I would pull it and check for burnt or missing traces on the printed circuit board.

Make sure the light in the wall control isn't blinking. That would be an indication that the lock function is on. To turn it off, press and hold the lock button for 3 seconds.

Try these instructions in case they are different from what you have.

To have your lights come on automatically when you walk into an open garage, you must START with the lights ON. If you don't want that feature and you want to turn it off, you must START with the lights OFF.



To turn the feature on, turn the lights on manually with the wall switch, then press and hold the LIGHT button for about 10 seconds until the motor unit light bulbs flash. Now, if the light bulbs are on, manually turn them out and then walk out through the open door. The light bulbs should come on.



To disable this feature, start with the light bulbs OFF and everything else is the same.

On the end of your opener where the small gray antenna is you will find an LED that flashes rapidly when you use your remote. When you release your remote it should stop flashing rapidly and just occasionally flash. See if this continues to flash rapidly while the bulb is on and your remotes are inoperative. If it does, remove the bulb and do the same thing. I have a feeling your light bulb is radiating.

On the side of the motor unit you will find the 'down limit control'. Using a small screwdriver turn this control in the same direction as the arrow printed on the cover. Some tweaking may be necessary to get it just right.

Garage Door Wont Close Craftsman 1/2 HP (1998)


What it is is the electric beams at the door are getting blinded buy the sun or out of line. They are the two black boxes on both sides of the door about a foot from the ground. Put a piece of card board in front of them not blocking the beam dut to block the sun. All that they are is safety beams for kids so they do not get hurt. If you have to move them to the top where the sun will not hit them. Sorry to say though you can not remove them all the way. Also make sure the lite on them is not blinking if so they are out of line.

Good Luck and Please Rate FixYa!
