With the icemaker removed, the voltage at th input harness is 75 Vac. Does this make sense? All the icemaker resistance readings are in acceptable range.
ANSWER Kramer, You will need to check the voltage at the I/R ice maker sensor assembly behind the control switch/panel on the right wall of the freezer compartment. The 4389102 control boards supply the voltage to the ice maker, 75 VAC, is not enough voltage to operate the ice maker. There should be 120 VAC on the black wire, pin#3 at all times, When the I/R sensor sees there is a need for the ice bin to fill, the voltage on black/white pin#4 will incease to 120 VAC and supply the voltage to the ice maker to run/cycle.
