My ice maker (Daechang DA97-11092B) is completely dead. The test buttom does nothing, no water fill, no motor activity. How can I trouble shoot this to tell if the problem is the ice maker or the main control board. I am ignoring the water control valve, door switch (the lights come on and go off fine), and temperature (-4) for now as unlikely.
I would also like to get a full service manual, not the fast start version.
Any ideas?
