Electrical Wiring in the Home/burnt garage light scoket


I have half horse garage door motor with two bulbs. At the end of both sockets around the threads there are burnt marks.The bulbs that are in it are those spiral bulbs.Could this be the cause of the burnt marks,or maby something else?
         Thank You in advance

Glenn  I am trying to picture burnt ends on these sockets,  I am assuming the outer threads at both ends are charred to some degree,       if so,  I think you have the answer,   most of any "older" garage door opener was designed for incandescent bulbs,  if you are using the spiral shaped CFLS  they often do screw in further than the threads on a regular bulb   

If the element is close to or touching the threads that is the problem   

About the only other thing it could be is the overall wattage if two high wattage bulbs are used  then the covers are put on the ambient around the bulbs increase,   so make sure the wattage is no more than designed for your opener,   normally 60-75 watt max,   

But I would think you would have charring in more places than just the end threads if that were the case,     

Try swapping out for some normal bulbs  you can still get 60s new  and flea markets often have now banned  75 watt normal bulbs if that wattage is acceptable         

It overall sounds like the spiral is too close to the plastic threads and causing the issue,  

let me know if that makes sense and how you get along   you dont want anything melting or charring,   it forms carbon tracks and the next thing is carbon tracked to the contacts and a short      along with the obvious fire hazard   

Depending on your opener configuration, you might be able to take the plastic out and put some ceramic bulb holders in the place of the plastic,  if enough room there are also extenders you can get but often there is not a lot of room between bulb and cover,   Will
