Fellow techs,
I have this Panasonic NN-8507 microwave combi in for repair. Every separate
function seems to work.
But when i use the combination button, micro and heater together, it seems
to go well for 4 minutes...then on the display i get 'FFFF' and the
microwave stops functioning.
I can only see 2 temp. controllers and 1 humidity(steam) sensor. The
temp.controllers seem to function allright using a lighter to heat them up
and they both switch off when getting too hot.
What else could cause this FFFF in the display?
(ps: I am an electr. engineer and thus aware of the dangers inside a
microwave, dont worry.)
Tia,
Mark
