Residential Ceiling Fan Issue

[dmcgth7]

Hi Everyone, I have a weird issue that I have never come across before...I have a customer who has a ceiling fan in their kitchen area that continues to prematurely kill light bulbs. They have had the fixture replaced twice in two years (prior to them calling me) they've tried different led bulb brands and still have the issue. The voltage is normal and there isn't anything odd with the neutral either. No other load on this circuit is having this issue. I will also add that they initially hired me for a service upgrade to 200A for their addition and the problem with the fixture still persists. Any ideas or suggestions are greatly appreciated!

Thanks,
Drew

LED are very susceptible to voltage variations and transients causing shortened life span. Being there have been multiple fixture changes would suspect its not necessarily the fan/light. But the fan can cause vibration that might cause premature bulb failure, and then the motor might be introducing transients onto the circuit that would likely require a PQ meter to see. Some fans are worse than others.

Thank you for your input Fred!

They make bulbs especially for fans and garage door openers because of this. Look for them.

Does fan stop when light is removed, or fails, with same fan-model replacements ?

I think the common denominator would be the same person screwing in the bulbs. It can be very easy to smash the tab in a light socket and I've seen it hundreds of times.

I know you said you got good voltage, but that doesn't tell you whether or not you're making good contact between the tab and the bulb.

Is there a possibility switching to an integrated LED light kit?

The only time I’ve seen an LED fail on a fan is when the fixture was a fully enclosed globe. I figured it was caused by heat along with vibration. I replaced the globe with an open shade and no more failures.
