1/2hp Craftsman Garage door opener light bulb

The light will not come on when the door is opening. I've replaced the bulb, and that's not it. And when I stand in front of the electric eye, there's still the click,click,click from the unit, just no light going on.

If you are getting a click the relay on the board sounds like it is working. Sometimes the contacts in the light socket gets burn spots on them. Try unplugging the unit, unscrewing the bulb and with a small scrapping tool (small flat screwdriver) scrap the bottom contact and the contact on the threads. Bend the contact on the threads a little too make better contact with the bulb. Screw the bulb the bulb in completely. If this does not solve your problem the only the left to do is to replace the logic board.

Craftsman 1/2hp garage door opener works fine to open door but to close I have to hold button down. If not, door won't move and lights flash 10 times.


10 flashes mean sensors are obstructed... something is in the way of the door or they are not facing each other. Clear the obstruction or realign the door and it will work.

Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. If the transmitting sensor light is blinking it is bad.

Have you tired reprogramming the remotes to the opener?

The opener receiver board may have failed, which happens. You can order a new one from Sears or other places on the Internet, and they are fairly easy to replace.

Once replaced, you will need to program the receiver to you remotes again.

I have a Craftsman 1/2 HP model #13953975SRT1.


It is normal for it to blink randomly. If you watch it while you press your remote you will see what it looks like when it is receiving a properly coded signal.
