This is a built in microwave with a push button to open the door. Push button won't work and door won't open.

It may be a broken door open lever or a worn or broken door open button.

If it's an owner the range type, you can likely get to and replace the door latch parts by just removing the control panel assembly.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If it's a counter top unit, you will need to remove the outer cover to get to the door latching parts.

Once it is apart, you'll be able to see how the door open button would press against the door open lever, which would then lift up against the door latch heads (hook-like projections on the door) and the door should open.
