Question about Kitchen Ranges
Most probably its an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.
With these units it would probably be outdoor PCB fault. On the outdoor PCB there are 2 communication channels for both of the indoors. You can check on those terminals if they supply similar voltage to both indoors. If the signals are the same, it would be the indoor PCB, if not, outdoor PCB.
Let us know if you have something more to know else accept the suggestion.
