How can I fix my microwave door that is stuck shut?

They do not normally have a locking system, just a latch, which operates a microswitch, so system knows door is closed. If not already done, switch it off, unplug it, see if that works, give a good pull, might be just stuck. failing that after unplugging, you would need to take the cover off, to get to the inside part of the latch.
