Broke some fins on bathroom extractor fan

rentalforever

I broke a couple of fins on the bathroom extractor fan and it now makes an annoying sound as I guess the whole thing is now unstable. This might be a physics-fail but I'm thinking that if I break the opposite fins on the fan, this will help to stabilise it a bit?

This is likely to help, but the fan will become next to useless. You can just switch it off with the same effect.

They are cheap enough normally , just replace.

But Im not convinced breaking more fins off will balance it

The more you break the less effective it will be. Time for a new fan, or at least a replacement part if you can it.

It's an Ecovent Silent and it doesn't look like the part is serviceable so have ordered one but it probably won't arrive for a few weeks given the state of things. Was hoping for a temporary/mitigating fix to ease the sound until the new one arrives.

Yup - try 'balancing' it :-) It will help.

Hasn't it got an isolating switch?  Should have..

The switch often operates both the fan and the bathroom lights.

Well yes, but I think Coffeehound is referring to the fact that it should have an isolator independent to the light switch.

Why independent? If the fan (with a timer) is activated by switching the light on, then the isolator switch switches both the light and the fan off. At least that's how it works in my house.

It's separate because

1. it's 'isolator', i.e. disconnects both live and neutral
2. a fan with timer has to keep working when you switch the light off

Perhaps it's a more recent addition to the Regs, but I thought fans should have their own isolator
