If this is new, return to the place of purchase, causes, defective magnetron, bad inverter board, and possibly keypad control board.

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

With the symptoms you
have, I would most strongly suspect a failed high voltage transformer, which is an expensive fix.
It may also be a shorted high voltage rectifier
diode (which costs less) or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.
If you or someone you
know
decide to look into it, we have critical safety information and
disassembly information at our site, and our link is at our listing here on FixYa.
There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating components.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.
Here are some links you
or someone you know can use for test help, but read their safety
warnings first:

(if it's not shorted or burned, it's
probably okay)

You can
download Frigidaire / Whirlpool owner's manuals and installation
instructions here.
They make removing the oven from the wall for service (or replacement) much easier.

This is a sure sign that the MAGNATRON needs replaced (this is what heats up the food) if every thing else works but food not cooking! 99% of time it is the magnatron!
Please rate answer!

In all likelihood the mangnetron has failed, or perhaps even something in the Power Supply. or a fault that is shutting the system mangnetron down, for safety reasons You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.
