1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

Had the same problem on my Samsung SMH9187. The two latches are cheap plastic.

Look for the SE error to happen next, its not made very good.

First you have to remove the trim from the top, there are two screws holding that and then a bit of gentle prying/wiggling. If you're having trouble with the unit randomly resetting, try torquing the exposed screws behind the control panel. The important one is probably the grounding point. It seems to have done the trick for me, three weeks and no SE- codes.
