Mr. Wieck don't you think this one falls into "hideously expensive to replace"?
Given that a luxury microwave oven costs around 300‚¬ and this one costs more than 700, I'd say it does.. there are almost no more expensive combi ovens in the market: other cheaper ovens I owned lasted 15 years and such.

I would be happy to buy another one and avoid complications, but I cannot afford it, and I am trying to understand the implications of the choice to self-repair it.
I know that there may be serious injuries ahead, that's why I am gathering informations here and there before taking any further step..
Thank you

Apparently (or should I say supposedly), this magnetron replaces the one in your unit:

About 100E with freight. Are you sure the magnetron is bad? A lot of things can prevent it from being powered up: door interlock switch, control board problem, burned relay (or connection - not uncommon on Whirlpools), HV diode or HV capacitor.
