The main board controls everything except compressor overload. It doesn't shut the comp down except for defrost. If no fans were running it may have been in defrost but that's kind of a lucky timing and if it was warm inside the cabinet as well something else is going on. If the condensor fan restarted then it should also want to run the compressor. It has the same overload that compressors have had for years, you are right that is what you heard click off. It'll cool down and retry like they always do. Might just be a bad capacitor or start device.

Think of the board as the timer, it just tells the comp to start and stop. This one is still even a standard Embraco reciprocating compressor so its 120v to compressor instead of the variable voltage linear comps we're seeing now. I'd check amp draw on the compressor to see if it is a bad compressor. Diag is pretty much the same as the past. There will be onboard computer diagnostics from the front panel however. They may not be any use in this case.

See if this link will work for you, I think it's the one.
