Bathroom fan fuse question

[pirate]

This house was destroyed completely yesterday. My pal who is the next door neighbour told me the fire was caused by a bathroom fan...the same pal I fitted a new bathroom extractor fan for a few weeks ago.
He seemed slightly concerned...
Do all MI's require a 3A fuse these days? If not, would you fit one anyway?

I don’t expect any overload current on what is essentially a fixed load.
The point of it stalling is valid I guess

Must be, I can't think of any other reason for it. It'd be interesting to do an experiment to see how much current these fans pull when stalled.

Many thanks to all of you for your responses to my query. Based on only hearsay evidence, i will try to ascertain the exact cause...rumours abound in such cases. If my bathroom fans went on fire (2 of them, installed by a "bathroom Fitter" with no isolator, no fuse etc) there is nothing combustible in the bathrooms themselves, so only a fire caused by overheated cables elsewhere could cause such devastation.
anyway, I'll update if I can, but thank you again for your replies.

It gets difficult...
Fan has stopped spinning and still buzzed, but customer doesn’t do anything about getting it fixed.... or even isolated.
6 months down the line, fire!
Investigation shows fan overheated. “Which wouldn’t have happened if there was a fuse”

I’m sure the motor could heat up over time, not enough to pop a fuse, and still ignite any dust that had settled on the non spinning blades.

6 months like that, now a 3 amp fuse makes sense haha
