Yes, has to be the favourite.  Even when it starts it only runs on two 
pots for the first few seconds.  Grounding the connector runs the fan, but I 
haven't heard it run on its own for ages. I've now got the thermoswitch 
suspended in a fan oven with leads coming out to a multi-meter -it still 
switches, but I think at a much higher point than the specification 85C.

I'll try replacing it.
