recessed ceiling fixture, dead or intermittent

Описание: A recessed light (flush to the ceiling) goes off sometimes and later works again. This is probably its built-in safety "cutout" or "thermocouple" keeping the light from overheating. It is telling you that the wrong style or wattage of bulb is being used or that ceiling-space insulation is too close around the light.
the part is called a thermocouple you should bring the old one to the electric supply to match up with correct replacement.

Have you ever tried to change a light bulb that has been on for several minutes? Did you burn your fingers? Light bulbs get extremely hot. The surface temperature of a bulb can be hundreds of degrees.
This type of heat can cause fires. In fact, many residential fires have resulted from improperly installed or modified recessed light fixtures. This is especially true in older homes that have old recessed light fixtures. In these situations, homeowners have mistakenly covered older fixtures with insulation. This insulation traps the heat created by the bulb. This heat, in turn, can either melt the insulation on the electrical wiring or ignite combustible materials near the fixture.
