Kitchen Aid 4450786A (Microwave/oven combo). Unable to use Microwave. When door is closed, it still reports that is open and will not allow to start. Is there a latch or sensor that needs to be replaced/repaired?
There will be a technical sheet hidden behind the controls which will help you locate major components.
The marked diagram below shows you the various parts that can fail and what effect will result.
You can find helpful exploded view diagrams and order parts by part number here.
Check the two fuses first, then if you have to check the cavity TCO, you will likely need to remove the oven from the wall.
If for some reason you don't still have your installation instructions, you can get them - and the parts list - here.
SOURCE: Directions to remove and open door panel to repair safety door latch.
You don't have to remove door to remove panel. Panel is held in by an outer plastic retainer which can be removed by carefully prying with a small screwdriver. I can be replaced by pushing it back in place after repair is completed. If you cannot open door from the outside, remove cover and you can see latches. Pry up on latch which will let door open.

Do you still have the piece that broke off? If so, you may be able to use two part epoxy to glue it back in place. I did this with a colaric MW and it did the trick. The latch was hook shaped and made from a hard plastic. Pete

The door handle is a simple repair that can be done with the door in place, or with the door removed. You do not have to uninstall the oven if this is an over the range model.
If you have any questions, please post back and let me know. I hope this helps you
