What is the wattage?

It should be listed along with the model and serial number inside the door frame or on the back side...

If it doesn't list wattage, Volts X Amps = Watts.

Hi Bart,
As far as I know the serial will not help,
If you reached the label on the back with the serial
you should see there also the mode.
And maybe aslo details on the microwave like the wattage.

600 watts

It’s 1200 Watts. Don’t listen to William miller’s answers. For some reason he’s talking about a ge microwave

600 watts

I checked the wattage for a replacement magnetron and it is rated at 900 watts'

Best regards, --W/D--

i just checked my R-3A36 manual to find out the wattage. it's 800 watts. i make pralines in my microwave. i am always asked for the recipe. so i needed to be able to tell people the wattage of my oven so they can adjust the recipe to their oven.
