can light fixture resized 600You turn on the bathroom light fixture and all is well until the fixture “clicks” and turns off. This is actually pretty common. In most cases, the fixture is getting too hot and turning off. There is a high temperature limit switch that does this. So how can you fix it?

\

The fix is to lessen the amount of heat getting to the switch. This can be accomplished in a variety of ways.

\

Heat commonly builds up from standard light bulbs. Flood-type bulbs seem to be a common thread. If you like that style of bulb, you can lower the bulb closer to the floor, which is further away from the switch. To do this you will need to remove the bulb and loosen the wingnut on the side of the can fixture. This will allow you to slide the socket up or down. You want to move it down, but not so far down that the bulb sticks out of the ceiling. Move it down a little and see if the problem recurs. If the fixture does turn off again, you can move the bulb down a little further.

Probably the easiest thing to do is to replace the standard bulb with a bulb that doesn’t generate as much heat. You can use LED bulbs or CFL (compact florescent) bulbs for this.
