LED light in bathroom flashes when extractor fan TP pole switch is closed.

[HappyHippyDad]

I have just fitted the manrose humidity/timer remote unit into a bathroom (see pic below)



When I switch the LED bathroom light off, it starts flashing. If I switch the TP switch for the extractor fan off it stops flashing. This only started happening when I introduced the humidity/timer remote unit.

I could understand if the LED light stayed on dimly, but why is it flashing? My idea was to fit a 230V snubber across L-N of the light, would this work? Is there a particular rated snubber that I need?

Could I just fit 2 x 160Kohm 1/4w (230V) resistors across L-N at the lamp?

Would these be suitable:

Just measured it. It was 95NF so 5% less than it's rated farad which I'm guessing is fine?

Yes, mostly they are 10% or even 20% tolerance.

So any thoughts on why the snubber did not work in this case. Would you then need more than 1 snubber or a different rated one?

Did the snubber change anything?

Some DC leakage by a controller would not be shunted off by a snubber, so this might just be a reason for it.

No, it did absolutely nothing. Thanks for all the input pc1966
