Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

did it work later???if so the thermal cutout was hot and needed to reset otherwise it could be the fuse,h.v. diode,h.v. capacitor,or the magnetron,the first three are cheap, the mag is not,let me know

I'm sure the magnetron overheated and tripped the magnetron's thermal cutout.
I'd strongly suggest taking it back if you can.

Generally speaking, charcoal filters should be changed and grease filters should be cleaned about every six months, or whenever you notice they are getting dirty & clogged. Yours will likely have one or the other - probably not both - depending on whether it's vented or it recirculates.
A clogged filter will cause the supply of cooling air flow to be lessened, allowing the magnetron to overheat. It only takes one severe overheating to damage or destroy a magnetron.
One common way for a magnetron to fail is that its heating power is less and less, then it just stops heating.
Magnetron's will usually have a warranty of 5-9 years, but you'd still have to pay the installation labor.
You can save a $75-90 home visit by removing the oven form the wall and taking it to a local Whirlpool-authorized warranty servicer.
The date of manufacture will be on the model tag in the unit, and the warranty terms will be in the owner's manual. Many manufacturers will use the serial number and date of manufacture to validate the warranty in lieu of a sales receipt.
