When I hit the test button it cycles and it puts water in the ice mold. The ice maker (compartment) fan works. The temperature is good. The water valve works. The ice maker rotates when testing. Control board or ice maker? Which do I order? I have the ice maker figured out, it's the 9 cube version. Would I change the inverter board or the main control board? Does this unit even have both boards? I don't know why Samsung can't be more specific with their parts. I looked this model number up on Sears and it called for the 7 cube version. The wiring harness is different on 7 cube and the unit actually has a 9 cube ice maker. It may be better to just stop working on Samsung all together.
