Craftsman Door Opener problem

Posted by barry92 (My Page) on

Just bought a townhouse that has a Craftsman 1/3 hp opener, model HBWO777. It works fine, but the lightbulb on the opener does not light up. Put new bulb in, still no luck. The pad on the wall is the three button. One says "Vacation", the other "Work Light" and the big one is for opening the door. There is a little red light that comes on behind the pad that says "Vacation" but nothing lights up behind the one that says "Work Light". There are four terminals with wires running to the opener on the back of unit. Any help is appreciated.

does it light when the door opens?

also, are you using a regular bulb? i tried putting a CFL in my openers once and they won't screw in far enough to work. put in a incandescent it works fine.

if you are using a known good incandescent bulb, then i would think maybe the socket is bad or a broken wire.

No, it does not light at all. I spoke with a GDO guy and he says he has never seen one that does not work unless it was struck by lightening. What is odd is that I found a User Manual online and it references just two connections coming from the wall control (bell wire), one red and one white. There are four coming from my controller.

You have an older model that had 4 wires from the wall control. Try unplugging the unit and using a small screwdriver pull out of the center connection of the light socket. Sometimes this will work. The relay that controls your light may be bad.
