Craftsman Garage Door Opener

stevemgdoJuly 28, 2007

I have two Craftsmen GDO's, one mfg @ 1988 and the other on/after 1990. I replaced the incandescent bulbs with the new "curly topped" flourscent ones and the older GDO would no longer respond to commands from the remote whenever its lights were on. So, when I opened the door from the remote, I would have to wait for the lights to time out before I could close the door from the remote and vica versa. When I unscrewed the flourescent bulb on the circuit side enough for it to remain off, the GDO would respond to commands from the remote even though the flourescent bulb on the opposite side of the GDO was on. Currently, I have an incandescent bulb in the circuit side and the flourescent in the other. Though these two GDO's are practically identical, the newer one does not have this problem. Does this sound like some type of radio frequency interference? Does anyone know of this problem and a fix?

I will guess there is rf interference from the bulb, is it the one closest to the receiver?

It must be the new bulb. Go back to incandescent and see if it doesn't eliminate your problem.

OK, replaced flourescent bulb with incandescent - only on the circuit board side (receiver) and it works fine. Now, is there a way to shield the receiver from rfi generated by the flourescent bulb? I first tried wrapping aluminum foil around the porcelain base of the flourescent bulb and connecting it to ground via a short length of wire. The remote then operated the door but only from a very short distance - under 15 feet. That's when I gave up and put the incandescent bulb back in.

I don't think you will be able to block the interference. The board is just too close. Maybe try a different florescent bulb there.

OK,I'll try to find either a different shaped one or another brand. Thanks.
