Ceiling Light Bulb Problem

Hi, I have a house built in 2007. For a while now, one ceiling light in two bedrooms that are next to each other have been flicking off and on once in a while. The light will go off for anywhere from a few seconds to a few minutes, and then come back on. Until recently, it was always the same lights but lately, in one bedroom, some of other lights (there are four in each room) have been going off and on by themselves also. I had an electrician here to do some other work, but when he was here the lights were working fine, so he offered no help. Suggestions?

You need to check all connections on the circuit, lights, switches, receptacles. Any back stabbed wires need to be moved to the screws. Any wires nuts removed and insides and wires inspected for corrosion or just replaced with new wire nuts.

Just wondering....are these can lights mounted in the ceiling? Could be they are tripping the thermal switch. Can you remove the bulbs and look for any labels on brand /model and max bulb wattage?

If they are canned lights, go into your attic and make sure all the insulation around the outside of the can is pulled away from it. Insulation will hold in that heat and contribute greatly to activating the thermal switch.

IF they are can lights and IF the thermal protector is turing off the lights, the lights won't flicker, they'll just go out for several minutes till the mechanical thermal protector cools and the cycle will continue. You probably have a loose connection somewhere, possibly on a neutral.

This would only be necessary if the housing were not listed and labeled IC for insulation contact. Otherwise the correct bulb needs to be installed.

Thanks

Thanks, all. They are can lights, but they should be the correct wattage. But perhaps if it is the thermal switch I could just put a lower wattage bulb in?
