E12 normally indicates a door switch problem. It can be a bad switch or switch mount.
Sometimes it's bogus and you can clear the code by unplugging the oven for a few minutes then resetting the clock.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door hooks latch when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
