Changing overrun on toilet fan - taking cover off?

rexmedorum

We want to change the overrun on our little toilet fan as it stays on for a very long time, but I can't even figure out how to get the cover off without breaking it It says "Greenwood Airvac" on the cover. Any tips?

Hi,

couldn't get picture link to work, what model is it?

There should be a wee screw at bottom, or maybe a slot either side where you can insert coin to prise open.

I have no idea what model, just bought the place. I can't see any screws or slots

A little searching on Google produced this. Not sure what your exact model is but they are usually similar.

Scroll down and click on the image.

Push in the little square piece of plastic in the slot. Sometimes you just have to "spring" the cover off by making it wider with your fingers so it comes off the internal spigot(s).

Got it! There was a tiny screw on the side at the back, very inaccesable. Took the cover off, it is a 100XS-T. There is a time +- sign but nothing to screw on it and just circuitboard and cables underneath. Now that the cover is off I am tempted to change it for a quiet one as the noise prompted wanting to chnage the time in the first place.

I'd just wee during daylight hours if it were me, or in the dark
