I have ceiling light fan. The fan works fine. The light used to work fine. All of a sudden one day the light started acting up. When I turn on the switch, the light flickers on for about a second and then turns off. It has three bulbs, all turn on and then off in less than a second. Any suggestions to fix problem.
I've seen this happen before. The vibration of the fan loosens connections to the bulbs. The lighting portion of the fan should be removed and examined for flaky connections.
The fact that the lights come on and then off might indicate an issue with a partially-inhibited connection that is generating some heat and then separating somewhere in the light fixture.
Does it have a remote to control the light and fan? I have found when adding remote units to fans that when the unit is powered up by the wall switch it briefly flicks on the bulbs, before either turning them on or off according to the last setting before the wall switch was flicked off. I have resolved this in the past by changing the LED bulbs,, but I don’t know why some do it and some don’t.
