New Bathroom Extractor Fan Smell

[Crinkmeister]

OK - problem solved. Turns out the fan was innocent after all. Guilty culprit was the ceiling mounted shower DP isolator. Surprising since this hasn't been touched for > 2 years and my Mk 1 funny smell detector (nose!) did not pick this up when my son first reported the pong over a week ago. Today, I noticed some slight discoloration on the isolator body. Switched off supply and removed switch to find supply neutral connection rather black with some insulation damage on the cable. I would say that the screw was not tight enough as it came undone rather too easily for my liking. Cut cable back to sound material, replaced earth sleeving, bought new switch and Robert's your mothers brother. Happy days, but I missed the Russian GP!! Thanks for your comments.

Sorry I think my picture is too big - not sure how to change it yet.

Very common problem with high current pullswitches. Chances are the original installer had it tight but all the strain on the terminations trying to get the damn wires back into the box often loosens the connections. In the days when terminal tunnels were deep and had two clamp screws this didnt happen.Manufacturer cost cutting is the culprit.
