Section G - Ice & Water Dispenser
To test the input voltage from the door harness to the dispenser and the output
voltage to the Auger Motor, Solenoid, Water valve and Extra Ice feature if equipped
use the connector on the left side of the Power Board shown in figure 39. To Test;
1. Check voltage between 120 VAC and
NEUTRAL for input voltage to the dispenser.
Should read line voltage.
2. Check between NEUTRAL and CUBE to
check the power to operate the cube ice
solenoid. Should show O voltage until the ice
actuator is pushed in, then should show line
voltage.
3. Check between NEUTRAL and AUGER to
check the power to operate the Auger Motor.
Should show O voltage until the ice actuator
is pushed in, then should show line voltage.
4. Check between NEUTRAL and WATER to
check the power to operate the single coil primary water valve and the Yellow
coil of the secondary water valve. Should show O voltage until the Water
Actuator is pushed in, then should show line voltage.
5. Check between NEUTRAL and FICE (Fast Ice Feature if equipped) to check
the power to operate the 2 watt 115 V heater on the freezer control cap tube.
The board will pulsate the heater so it is on 50 % of the time for a 12 hour
period of time. (Should show O voltage until the Extra Ice button is pushed,
then should show line voltage.)
To test the voltage from the power board located in the dispenser to the control
board located in the front face plate use the low voltage section of the power board
as shown in figure 40. To test:
1. Check voltage between GND and V - IN for input voltage from power board to
control board. (Should read 12 VDC + or - 10% voltage.)
2. Check voltage between the two terminals shown in figure 3 under LIGHT for
testing power from the control board the relay that operates the dispenser
light relay.Should read 0 voltage until the light switch button is pressed or a
actuator is pushed in, then you should read 5 VDC + or - 10%.
3. Check voltage between the two terminals shown in figure 3 under WATER for
testing power from the control board the relay that operates the water valves.
(Should read 0 voltage until the water actuator is pushed in, then you should
read 5 VDC + or - 10%.)
4. Check voltage between the two terminals shown in figure 3 under CUBE for
testing power from the control board the relay that operates the solenoid.
(Should read 0 voltage until the ice actuator is pushed in, then you should
read 5 VDC + or - 10%.)
