recessed light problem

Posted by nickt (My Page) on

Hi, I have several recessed lights installed in the cathedral ceiling of my office. A while back, one stopped working. I think it blinked occasionally before going out (but not sure of this). I have switched bulbs with no success. I don't really know much about lighting/electrical, but I assume it is the ballast, since there are not many parts involved in these things. This a link to the housing with a schematic:

My question is can I change the ballast myself? I am handy but limited in electrical. Also, will I have to tear out some of my ceiling to get to the ballast? The drawing seems to indicate components inside and outside the housing. I can see the internal components after taking the cover and can off, but the other part is obviously inside the ceiling.

Any help would be greatly appreciated.

RE: recessed light problem

I suggest you buy an identical replacement fixture. You can use it for parts and can explore it to see what you need to do to make the repairs without tearing up the ceiling. The socket, thermal sensor or transformer can all be failure points.
