The door handle can easily be replaced without the assistance of a repairman. This is a common problem with some microwave oven doors.
This is not difficult. To access the door handle mounting screws on MOST microwave ovens, you have to remove the inner door panel that goes around the perimeter of the glass. You can use a small screwdriver to carefully pry the plastic up and work your way slowly around the perimiter of the glass. Most microwave ovens also have grooves in the panel that you can insert the screwdriver into. Use care not to pry against the glass. The glass is tempered and also has an RF shield that prevents harmful microwaves from potentially harming the consumer. If you break the glass, you will need to purchase a new door.

The door handle screws are located behind the inner panel. Simply remove the broken handle and install the new one. Re-insert the inner door panel carefully and gradually work your way around the perimeter of the door glass and make sure it snaps back into place.

If you have questions about this repair, please let me know. I hope this helps you. PS If you haven't purchased the handle yet, the part number is 5304464066 and can be found at searspartsdirect.com for about $20.
