Thank you both. Today I've taken the oven out of the kitchen unit and taken off the back and top covers - whilst both thermostats look the same from the back, one does indeed have a red dot and the other a blue dot. Thinking about this, that would equate to hot and cold...
The wiring loom seems to connect all the various components to the circuit board behind the display so there's obviously some electronic control going on, rather than a simple 'stat-controls-fan arrangement. The red dot 'stat connects to the probe inside the oven cavity whilst the blue dot unit is physically closer to the ventilation fan, so I reckon we have our culprit.
I have ordered the blue dot Stirrup thermostat and will report back with the results.
