Re: Hello everyone can you help me
Short answer: No, that is not possible.
Long answer:
For most microwave ovens, the power output of the magnetron tube cannot be adjusted. Its either ON or OFF. The cooking power is adjusted by turning the magnetron ON and OFF. The duration of the ON and OFF cycles depend on the power setting.
With that, it means the power dial is not connected in series with the magnetron tube. It is likely just a potentiometer that controlls whatever it is that turns the magnetron ON and OFF.
That means that dial is not designed to carry high current, which is what you want to do. If you connect it to the fan, magic smoke will come out of the dial. Maybe some sparks, too.
Just in case you want to know more about that timer module:

That link says 250vac ? Is this not the same as or speak it not mean that I could wire it to a 240v household plug and fan or is v and vac different?

It would be better if you told us what you want to do......What is the objective? A switch to control what. I might be slow but it isn't obvious
Why do you want to use the fan?
Do you want the fan speed proportional to the temperature?
Do you want the fan to turn on/off automatically with the cooker?
