How long does it take a microwave oven to warm up?


My Panasonic inverter seems to take up to 3 seconds to get going. That
device has a variable supply, which it can control heat output. Most others
are instant on.

Food still is cooking when power is off. As it cools it's also heating
cooler areas. Usuall recommended to wait one minute before eating. Enclosed
containers also equalize heating by steam. The microwave is a bit over 2
inches in length, so not all parts receive equal heating. There is usually
the rotating plate, but some have rotating devices in waveguide to spread
out the waves to also help equalize.
