Pot light failure


Three of four lamps work. There appears to be 12 volts to the failed lamp. Is it possible that the thermal protector for this lamp is broken?

How did you measure the voltage?
If the thermal was bad, you would not read a voltage.

Are they low voltage lights? Do you have the correct lamp? Are the lamps making good contact? If you wiggle the lamp in the holder do they come on? In some low voltage lighting, the lamp holders wear and and the lamp don't
make good contact.

If it is low voltage lighting, then it also possible that that transformer has gone bad.

Any of the above can be fixed and or replaced.

Appear to be low voltage. Checked the functioning lamps from other sockets in the bad socket, and they do not work.
Tried a new lamp holder and checked it with a bulb in a good socket OK. When tried in the bad socket nothing.
Is it possible that the transformer could fail only one of the four?

It probable that each light has it's own transformer and it could fail. Are they new work or remodel can lights? You should be able to remove the can housing and pull out the transformer for replacement.

There were a remodel several years ago. I was able to remove the pot from the defective lamp and there is nothing attached to it other than connecting wires.

For some unknown reason the defective fixture now works. The famous "loose wire?"

Were you able to see exactly how the wires entered the fixture and are connected to the socket? The loose connection could even be a corroded rivet that held the wire on or held two pieces of metal together.
