Wattage on my microwave

Most home Microwaves draw about 12-14 amps. You could figure your wattage at about 1680 watts. Calculated by factoring the voltage of most units 120V times the typical amperage draw of 12-14 amps. so wattage is volts times amps or (12-14 X 120) 1440-1680 watts

There should be a sticker or plate mounted on the door jam of the unit that will say what the wattage is. if not, contact the manufacturer with the model number and they'll be able to tell you.

http://www.sharpusa.com doesn't have your manual. But you can find it yourself on the
back of the unit - the wattage should be listed.

If only the amperage is given (you know the voltage is 120 VAC RMS), so using Ohm's Law, you can calculate wattage:

Watts = 120 Volts X Amps

There is no reference to this model on the GE website, but have a look at this webpage:

The wattage of this model JVM1851 is 1100W.

If the model is a counter top unit, you can check whether there is a plate at the back of the oven with the wattage on it.

The actual wattage rating for this unit is 1100w.

look on the tag on the rear cover and take your input voltage and current and multiply them for unit wattage i.e. 120 volts X 8 amps = 960 watts

On page 12 of the owner's manual next to the drawing of the unit, it says it's 800 watts.

Hi, this unit is rated 1000W. Here's a link to the quick spec sheet at GE:

Look on the back of it and you will see it. I would say 700 watts

Wattage is based upon voltage & current. I would think that on the 1300W unit, either the voltage or the current is higher than that which is used on the 1200W unit.

Perhaps the magnetron in the 1300W unit is being driven harder. Are the fans the same size?, The magnetron in the 1300W could be running harder and they have a larger fan in it.

In any event, if the part numbers are the same, you should have no trouble using one units parts to fix the other.

Good luck!
