LED Lamps and extractor fan problems..

[ash_s3]

A friend of mine has just replaced some halogen GU10 lamps in his bathroom with LED lamps from Amazon.

Hes saying since swapping the lamps, the extractor fan runs continuously. (230v in-line unit in the loft with over run timer)

He tried swapping one LED lamp back to halogen and it worked as it should, timing out after 5mins or so.

Removed the halogen (with the lights switched off) and the fan fired up by itself!

Anyone come across this before? Sounds like a resistance issue to me, would a resistor sort this out?

Cheers

Condensation trap needed methinks :santa_smiley:

This may, or maynot be helpful but....

Today I investigated a bathroom where the lights (LED's) stayed on when the lights were off!

So I removed the cover of the ceiling mounted fan...... and narrowly avoided being "drenched" by the build up of water (condensation) that had accumulated and clearly the moisture was providing the "connection" between the SL and L.

With the fan cover off, and the fan disconnected, the lights now work perfectly.

Hope this is of use to some of you!

Just wash away all our clever theories then!

I was just searching for a resolution to a similar problem. Changed some filament lamps in a Bathroom yesterday to LED. Customer messaged this morning to say the fan has been running all night and keeping her awake.
I am going back today to fit a "snubber" across the feed and switch line. Same as you would use when the led lights keep flashing. If you need one Google Danlers snubber.
I will post if it works, hope this helps, Cheers C.
