Peter,
Many, many thanks for that!

A = the £12.95 Heater thermostat
B = the £9.95 Manual reset cut out
The Exhaust thermostat is at the top of the
URL you sent.
There is a drop down selection of cut outs
on your URL. Any idea which I need given
that the number on the cut out I have is
7M94605600C. There doesn't seem to
be anything in the list like that..
I imagine the sensors all have defined temperatures
at wich they switch. Do you know if that information
is spelled out somewhere?
Would you advise I just replace them all while
I have it apart? Or is there some way I can
test these devices on the bench?
Many thanks for your help.
Roy
