I have a KRFC400ESS01 french door fridge with the ice maker in the top left of the fridge that's not making ice. The water dispenser works fine, the auger functions for ice dispensing, the ice fan and associated hardware seems to be functioning, but the ice cycle won't start.
Upon further investigation, a multi-meter on L and N in the ice maker module shows 0-1 VAC with the door switch closed. I verified continuity on the thermal fuse, verified function of the switch, checked wiring harness and checked in service mode, 192 shows "OFF".
I did go ahead and swap in a new ice maker module since it was relatively cheap, thinking maybe the old one had a short or something, but there's no change.
Tracing the wires back to the harness where it enters the ice maker area, I'm not seeing voltage. This seems to make sense as the service mode seems to imply that the maker is switched off....the question is why? Tracing the schematic, I think I'm looking at a new main board, but wanted some input.
Thanks!

Service Test - 192 Ice Maker State Test
Display shows dr if left fresh food door switch is in the door open position.
Display shows OFF if ice maker power switch is in the off position and door closed.
Display shows On if the ice maker power switch is in the on position and the door closed and heater is off.
Display shows OnH if icemaker power switch is in the on position and harvest heater is on and door closed.
