Broken torsion spring needs to be replaced

Guess you should take it to repair. It won't work with all those parts broken. Anyway, how I could help you?

Replacing the spring isn't very difficult if you're mechanically inclined.
You're basically removing a few screws, the front panel of the door is removed exposing only the glass part that's still hinged. The springs are exposed. Hopefully one spring is still in tack so you can see the orientation of how to put the replacement in. It's not very intuitive on how to do this part.

Handle Actuator

If the microwave door won't open the handle actuator might be broken. This is a plastic part which can become brittle over time. This part is connected between the door button and the door latch assembly.

If this is the flip down door. You will need to take apart the side cover of the unit to fasten the spring. Once you have done that you need to put a pen or something to hook it so it doesn't drop down in the unit. If you are unable to hook the spring in the door. You must take the outer cover off the door to hook the spring and then replace the cover. You may find this to be a two person job and may be easier to hook the door before you hook the unit. Some doors are different then others.

You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

In most cases, the spring mount on the inner door panel breaks off, and while the ideal way to fix it is to replace that whole panel, the time, cost and labor are considerable.

It's usually easier and cheaper and just as effective to use epoxy and some kind of hardware to fashion a new spring mount.

Or if there is enough material to drill a hole for the spring, do that, install the spring, then add a dab of epoxy to cover the bottom loop of the spring where it goes through the hole you drilled.

Let the epoxy dry overnight before you close the door or use the oven.

I had a tension rod break in my door as well. There are two of them that cross forming an X and you can see them when you open the door and look in the crack. Fixing them is very easy once you get the outer panel w/ glass and the black molded plastic piece off. WARNING, when you open the door there are two screw on the inside top part of the door assembly. THEY ARE THE ONLY TWO SCREWS HOLDING THE ENTIRE FRONT PANEL/GLASS ASSEMBLY IN PLACE. I found this out the hard way. When the 2nd screw disengaged the whole assembly came crashing down shattering the glass and nearly cut off my toe. Be very careful when taking off the outside panel!!!

Next challenge...the black molded piece that also needs to come off. To remove this take off the piece that surrounds the exhaust tube to get at two screws that are directly underneath the molded plastic piece. After getting that off you have access to the two rod and can get them installed without to much trouble.

Again, be very careful when removing the front panel. My repair went from an 18 dollar tension rod to a $200 dollar front panel and nearly cost me a toe (yes, I was barefoot).

As I suspected, there are 2 torsion springs in the unit associated with the door. Sounds like one or both has broken or come out of place.

That prevents one or more door switches from being activated properly, and such excessive or intermittent switching can damage the switch, resulting in a lack of heating.

While I didn't find service data on your specific model, model KBMC140HBL0 is similar, and you can see helpful exploded view diagrams of it: http://tinyurl.com/gv383

There should also be a "mini-manual" either on the rear of the unit or hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Unless you or someone you know want to tackle it, I'd say you should call for service.

Good luck.
