Question about Panasonic NN-T783SF 1350 Watts Microwave Oven
The unit looks normal with display/control panel on. After selecting cook time and pressing start, light and sound came on as if it's working, but after a few seconds the unit shuts off as if time is up. There is no hint that the food had ever been heated up before.
With the lid opened, I can only see one fuse, which still checked out OK (thus display was still on). I suspect some relay decided not to latch, or high voltage did not come on, so controller shut it down -- but I don't know where to check. Please help. Thanks!

If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently
the microwave runs for a few seconds and stops the touchpad and
control panel might be defective. There are several other components
that can cause this problem, be sure to check any other components
before replacing this board.
the microwave runs for a few seconds and stops the touchpad might be
at fault. This is not common. Generally speaking, if the microwave
display is working and some of the buttons respond correctly but
some don't, the problem is with the touchpad.
