You can put a jumper between L and V and this will activate the water valve.
Modular crescent Icemaker test points:
With NO power to the icemaker, and
ice ejection fingers in the freeze position:
Your ohm meter should read 8800 ohms between L and M,
and 72 ohms between L and H.
With power ON to the ice maker:
If meter reads 0 volts between L and N you have no power to the ice maker.
If the meter reads 120 volts then you have power to the ice maker.
If you have 0 volts between L and H heater is off if you have 120 between L and H the heater should be ON. If you have 0 power between L and M the motor is off. If you have 120 between L and M then the motor should be ON. If you have 0 volts between T and H the thermostat is closed If the meter reads 120 between T and H then the thermostat is OPEN. If the voltage is 0 between N and V the water valve is closed. If the meter reads 120 water should be filling the mold.
