It may be a blown fuse or a bad thermostat / TCO on the oven cavity or above or on the microwave.
Yours should have a "mini-manual" (technical sheet) hidden either behind the grille or control panel. It is very helpful in locating and testing components.
There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.
Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
You can download Kenmore manuals and installation instructions at http://www.managemylife.com by clicking the Manuals link near the top center of the page. Then enter your full model number from the tag on the oven on the next page.

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Post a new help request with the answers to these questions as well as the full model number from the tag on or in the unit.

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:
http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on; use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

Usually some disassembly is required to replace the lamp

72189655 is the model number

I have a similar unit and I removed the outside of the door by loosening two flat head screws on the narrow where the handle is located. There are several screws yet holding the outside plastic housing too. Once these are removed the plastic door will come off. Then the handle will be accessible.
The same issue started with my oven too and I replaced the original handle with larger screws and using a high quality plastic glue.
This held for a while. The plastic door cover seemed to have changed dimensions during its life and warped. I ordered a new door and it lasted a short while. I then asked for a new door under warranty.
Bottom line they wouldn't sent a new cover but they returned my money. Apparently the doors all had crappy plastic issues. Currently we are using the microwave with out the door front. It still works like new after 10 years though.
