Having found an open primary in the small transformer ....

That's strange. Transformer primaries don't open very often. I would be
inclined to dig deeper to find out why there's an open circuit (internal
fuse open? Bad connection? Melted wire?) and whether there is any fault
downstream of the transformer (shorted component?).
Don't know the reason, but I have removed it from the board and there is
infinite resistance across the primary terminals and no visible damage
to the transformer or the board it's on. Fuse is intact. The unit
would be about 5-6 years old I reckon.

Mebbe it has a faulty or tripped thermal protector ?

Thermal protectors are fitted to prevent overheating etc. Usaully you
can by pass same, and "fix" them, but as theyre fitted for a reason( not
used to our extreme heat?) they often fail. The tranny suggested is
probly close enough.
