VOLTAGE READINGS AT GREEN COIL OF SECONDARY VALVE
When Ice Maker is Filling:
Voltage at Outlet Voltage at Coil
120 VAC 100 ± 10% VAC Normal
100 VAC 85 ± 10% VAC Normal at 105 VAC (Will require use of 50 watt coil)
100 - 120 VAC 20 - 76 VAC Bad connection, Fill Switch, or Heater in Ice Maker.
VOLTAGE READING AT YELLOW COIL OF SECONDARY VALVE
When Filling A Glass With Water:
Voltage at Outlet Voltage at Coil
120 VAC 119 ± 10% VAC Normal
100 VAC 99 ± 10% VAC Normal
100 - 120 VAC 0 - 90 VAC Bad connection or bad Fill Switch
VOLTAGE READING AT COIL OF PRIMARY VALVE
When Ice Maker is filling:
Voltage at 0utlet Voltage at Coil
120 VAC 56 ±10% VAC Normal
100 VAC 48 ± 10% VAC Normal
100 - 120 VAC 10 - 43 VAC Bad connection, Fill Switch, or Heater in Ice Maker
100 - 120 VAC 0 VAC Open Diode (if current is normal at secondary coil)
NOTE: Remember that with the current flowing to the Primary Valve Coil through the Diode, you are
getting 30 cycle current instead of 60 cycle current at the coil of the Primary Valve. Because of this,
your volt meter will only read about 1/2 the voltage that is going to the coil. The change in the cycle of
current does not effect the efficiency of an electromagnetic coil.

TECHNICAL NOTE: All readings are for 120 volt units. Similar voltage drops will be found on 220 volt units.
