I am working on a service tumble dryer at the moment and think yours might be similar (although not familar with that model). At the back right hand side, viewed from behind there is a plate secured with 4 self tapping screws behind which is the heating element, remove this carefully as the cable is attached(it can be allowed to rest gently on the ground). Now two thermostats are visable( they look like small round metal cans), reach round behind the right hand one and feel for the trip switch ( mounted directly behind). This is perfectly safe provided the mains lead is disconnected. Hope this helps if you wish to try.
