They don’t have thermostats, very few modern machines have them TBH.
Temperature is controlled by an NTC, its either a small round one located in the back of the drum backplate ot the rod type slotted into the heater itself..
Apologies I’ve probably confused in the process of the message. It was the NTC I needed. No matter where I look I can’t find it. If anyone can supply a part number it’d be awesome.
