I have a GFCI part I need to replace but it may now be obsolete. It was located in a 120 volt shower recessed light fixture. The GFI device is cylindrical, 3/4" in diameter, 2.5" long with cooling holes on one side. It plugs into the junction box knock-out of the recessed light fixture where it's wired into the light circuit. The leads are black, white and blue in color. I think this was installed around 1989 when the house was built. Can anyone tell me if these devices are still available and what their designation is. Thanks.

I have never heard of such an item as a GFCI part. It is most likely a thermal cutout sensor. You will need the name of the manufacturer of the fixture.

I notice occupation, is missing in your profile, It would be careless on our part to give advice on this issue, That device can be anything from a low voltage relay to an X10 type of device, if you are not sure what you have, it may be best to get an electrician to investigate.

LK is right. Without more information it would be foolhardy and irresponsible for us to give you an answer.
What leads you to believe this is a GFCI device? Is there a label?

If it doesn't have a test button it isn't a GFCI device. I am betting for low voltage relay.

Perhaps a thermal protector?

Thank you for your help. I'm a mechanical engineer by education. I believe it's definitely a thermal protector device since all similar recessed lights are also equipted with this device. My GFI inclination was due to the light's location in the shower and the fact I have worked with recessed lighting that wasn't equipted with those safety devices. The device is malfunctioning and I'm going to replace it. Unfortunately there's no manufacturer's name, only various catalog numbers. I'm sure the local electrical supply house will be able to help me. Thank you again.

Why fuss over a cheap tin can? Just replace the whole blessed thing.

It is genneraly far easier to replace the thermal switch than to replace the can. Especially if it was a new construction can.

Sure you're not using a too high wattage light bulb in it? Or maybe there's too much insulation in the ceiling touching it and allowing it to get too hot.

If one will physically fit, a compact florescent bulb may be a solution. Less heat for the same light output.
