Fixed light, then it stopped working again

9 years ago

I have two Halo2T recessed lights in my den, original to this 1976 house. One of them was out the other day so I tried changing the bulb, but that didn't fix the problem. After doing some research, I measured voltage to the socket which only read 10-12v. I changed the socket, checked the voltage (122v) and the light worked! The next time I tried to use the light it was out again.

Today I checked the voltage to the black and white wires and only got 9-10v. I seems like a wiring issue which is a pain because I only have access to the socket--the junction box is behind the ceiling. I'm curious though, why would changing the socket get me 122v, even for a short time?

Likely because the connection in junction box is poor. When you changed socket the wire in junction box was moved enough to reestablish contact. There was probably never a problem with socket.

A remodel can can be taken off to access the wiring. A new construction can can also be taken off there are screws inside the can that let it come off the mounting bracket. Or go into the attic if applicable. Need access to the can's wiring box either way.

Only situation I can think of where it is inaccessible is if the can's wiring box was spray foamed over and buried in the spray foam. That would require some demo of the foam to get to the box.

"...the junction box is behind the ceiling" probably means that it is in violation of the code which requires that all junction boxes be accessible. Do you think that's the case?
