My 27 year old microwave oven was down below 400W output and taking a long
time to heat my coffee.
So, I went out and bought a 1100W one.
Big mistake.
It works fine on coffee, but WAY overcooks small stuff.
Yes, it has a power level setting, but the on-time is 15 seconds
and they modulate the off-time.

Suggestions?

Put in a smaller high voltage capacitor?
Thanks for repeating one of my suggested options.
Can you be a little more theoretical?
One reference suggested that the cap is actually
sized to resonate with the transformer. That would make
the change of cap value much more sensitive than just a power
ratio.
Relevant input?
Thanks, mike

Get an oven with inverter power control, like a Panasonic?
Simple matter of price ;-)
