Bathroom fan burnt out.....

[-Matt]

Had a callout for a landlord as the bathroom fan stopped working.

Didnt take too long to work out why...

Never seen a fan quite as bad as this before!!

Wonder what caused this, possibly got jammed and overheated?

Found this one recently that's nicely got its own fuse, finally.

I always fit 3A fuses in fan isolators using click mode modules..If it had started a fire and gone to court the MI would say it states MUST be protected by 3amp fuse if the contractor hasnot followed these then responsibility could be past to the contractor. For the sake of £1 just i fit it!

How about holding the manfacturers responsible for not providing something fit for purpose? Unless its connected to a socket circuit then there should be no need to fuse it down, you dont after all fuse down all individual light fittings do you?

Odd, the coils visible in the photo don't appear to have been overheated.

Depending on ambient temperatures impedance protected motors of < 100 watts will generally reach up to 150 degrees Celsius if they're locked rotor for an extended period. That's hot enough for mountings to distort badly if they're PVC but not hot enough to cause much discolouration of the windings.

Interesting, do you think ZP is considered with the construction of a chuck away extract fan.

A lot of very small motors are designed and classed as ZP (impedance protected). ZP open frame shaded pole motors like this one are common, also a lot of computer type fan motors are also rated as ZP.

Light fittings do not stipulate being fed off a 3A fuse through a double pole isolator, i dont see light fittings as much of a threat to going on fire as a motor inside a fan. I agree the manufacturers should do more,,but in mean time cover your own derrière..

You never seen a ballast catch fire then? Plenty of them fitted inside unfused light fittings.

Mostly inside an earth metal strip light, and alot of these strip lights have fuses in the terminal connectors

As I said not all are, besides do you think a BS1361 fuse will blow before any protction offered in the DB?

Rental usually equates to "tenants don't give a ----" every so often I vacuum out the dust and crud out of my bathroom fan, I even take the grill off to wash it as it spoils the "look" of the bathroom.

People nowadays just don't care especially if someone else is paying, when I was a landlord I knew the from which countries I wanted as a tenant and it wasn't from here.
