Is it safe to put aluminum foil under the hot contact in my garage door opener light socket ? I have to bend it out every few weeks, because it loses contact with the light buib ?

For the lights, very common the contacts get flattened out and melted. I see this every day. Unplug the opener and let it sit for about 30 min. I never wait but just to be safe, let the capacitor loose its charge. With a precision flathead screwdriver or fingernail, bend the contacts in the light socket out about 1/8". Should help. Buzzing concerns me a little. May be an electrical issue. These openers use an AC brushed motor. They get very hot and in rare cases can catch fire. Theres gear grease and dust inside that has ignited in a few motors. There is an overheat switch built in but dont count on it. I would suggest buying a new machine. Find a DC motor with a belt drive. They last the longest and require the least maintenance. Marantec make the best in my opinion.

I would recommend a replacement light socket. I would not want to be responsible for a fire or electric shock if I told you "yes."

Set a step ladder under the power head of the garage door opener so you can reach the power cord and the lens cover safely.
Climb the ladder and pull the power cord from the outlet in the ceiling. Press the two lens tabs in to disengage the lens from the power head. The lens tabs are below the opener rail on the upper corners of the lens. Pull the lens cover straight off of the power head.
Unscrew the light bulb from the light socket. Use a new 60 watt bulb to replace the defective bulb. Do not use a short neck bulb. Screw the new bulb into the light socket just as you would a regular lamp socket.
Slide the lens cover back over the front of the power head. Push the lens cover in until the locking tabs engage the top corners of the lens cover.
Plug the Genie garage door opener power cord back into the ceiling electrical outlet.

disconnect the power and try to pry the prong in the socket of the light outwords,check the connection in the unit itself

You can buy bulbs designed for garage door openers. They are heavier duty. Also you should unplug the unit and remove the light bulb. Pull out on the center contact of the socket. Replace the bulb and plug the unit in.

Sounds like a loose connection inside the unit. When you move the light fixture on the motor and get it to light, the contact is reestablished, possibly being a loose wire. With the vibration from the operation of the opener, the connection will lose its contact again and the motor ceases to function. Have an electrician give it a look or disable it's power so that you can remove the cover(s) and investigate yourself.

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.

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.

We had he same issue and changed our bulb from a CFC back to a traditional bulb and the problem was solved!

Unplug the unit and look inside the socket. there is a copper lead you can bend up as it might not be getting a good contact. If that is not it you can start by replacing the socket itself from the manufacturer. If that does not do it then you will have to replace the logic board. Whether you reair or replace get a surge protector on this unit 900 joules or higher. Thanks BB
