That might be a good idea, thanks.

I've pretty much narrowed down where the smell is coming from - it's
coming from beyond that little screen (or vent) I mentioned before. It
is located on the 'ceiling' of the inside of the fridge, which then
seems to go towards the back of the fridge and then down presumably to
the drip tray. I checked the drip tray and there are no nasties in
there - a very small amount of water and there was a water droplet on
the drain pipe itself, so I don't think there's a blockage... but
maybe there is a partial blockage?

Another thing:

2 or 3 weeks ago, I checked the thermometer in the fridge, it was far
too cold (almost 0°C), so I adjusted the thermostat and then promptly
forgot about it. A few days later I realised the temp was now 6°C -
which is far too warm of course and again readjusted the thermostat.
Might be just coincidental timing... dunno.
