There is a timer and relay that operates the bulb. One or both may be the problem

Make sure the bulb is good. Unplug the opener and remove the bulb. Use a small screwdriver to pry out on the center contact in the light socket. Replace the bulb and plug in the opener.

Rather than new bulbs I suggest you unplug the unit and use a small screwdriver to pull out on the center contact of the light socket.

Garage door light...


Some of the newer light bulbs do not work well. Unplug the unit and look in the actual socket. There is a copper lead, pull it up a little and try it. If not then you can replace the sockets themselves. Although it may be the logic board too. Make sure and get a surge protector on this nit 900 joules or higher. Thanks BB

Main light on will not come on when door is opened/closed


For some reason, the bulbs I tested that worked somehow didn't work correctly when inserted into the door opener. We opened another set of bulbs we purchased and what do you know, the light now works. I don't fully understand as the other bulbs did work just not in the garage door opener.

Light does not come on when I open/close door, not the bulb


Good Morning:

I also substituted Floescent Bulbs for the standard bulbs. The bulbs would not light up although the relay was working. It seemed that the Florescent bulbs had a somewhat shorter neck. What I did was unplug the drive system from the outlet and then bend the metal connector in the socket so that it would come out further towards the opening of the socket. I then repluged the drive. The Floercent bulbs now have contact and are working perfectly. Simple problem with a simple solution.
