can light question
I've got a question for any electricians out there.
I've got a can light on my 2nd floor that is supposed to be rated for contact with insulation. So since it is in the attic, there is insulation now on it.
It would once in a while turn off after apparantely heating up too much- and later work fine when it cooled. Now it won't come back on at all (and yes the bulb is fine and no breakers tripped).
My question is whether the whole can likely needs replaced? Are the thermal sensors designed to trip and stay off or do I just have a bad one. If I can just change the sensor (from below-inside the can) and move the insulation away from the light I'd prefer that than crawling around in the attic actually swapping the whole can.
I know, the easy answer is to call an electrician but I do have skills in basic electrical. Changing a can light, which is what I'll do if I can't repair the old one, is well within my abilities.

It is likely the proclaim bulb holder got damaged, bad contact, metail oxidized..etc. and no longer working... My Dad's apartment have these guys damage by overheating... and I replace one of them by replacing the proclaim bulb holder...

probably going to be just as cheap and easy to replace the fixture rather than just the thermocouple. Just make sure it is an IC rated fixture

the proclaim socket cost $4 but the insulated can probably cost around $30 or more...

do you mean porcelin? socket?

KUIPORNG 04-18-2007 03:31 PM

I can't remember the spelling... porcelain it should be after checking the spelling...

those part where you rotate the light bulb onto...

the failure rate on those is near zero, if it was going off and coming back on after it cooled, it has a 135 degree thermocouple in the can, which by the way, a 6 inch halo IC rated new construction can is only 7.33 at the big box store.

My father condo has two of these guy fail and I replace one of them for him and it works... if it is close to zero failurer, you won't find such part in HD which I bought ...

then your father is using the wrong bulbs for the cans. Those don't just go out. And if you replaced it and it worked, then you probably took out the thermocouple as well. How long have you been in the trade?

The can light isn't costly itself, but where it is in the attic is the pain to get at. Its out near the edge where the roof is sloping down to nothing. Its not impossible to get at, but just a pain. What I was hoping was that I could get a replacement thermal sensor and just push the insulation away from the light with a broom or something to extend my reach. If not, I guess I'll just suck it up and get dirty laying in the blown in insulation to get at the light.

Recess can lights can be accessed from in the room that they light.

They come apart. It is not fun working in the small hole, but you can get to all the parts.
