"Power up unit / turn unit on
Ensure green indicator light on for icemaker
Place hand in front of freezer fan outlet and feel for cool air,
listen/feel for compressor, watch for interior light"
Their is no light. That to me indicates a failure from the power supply wouldn't you say?
I checked the cord and power is getting to the supply board.
Getting nothing from the touchpad, nothing running at all, no ice maker indication light, no interior light on, no nothing.
That to me points towards the main board.
