Fault Code 18
Reason:
The FC fan is drawing more current than is expected. Either the wiring is shorted
or the fan is faulty.
Primary Action:
Check the FC fan wiring and connections at both the fan and the power module.
Secondary Action:
Check the fan. If faulty, replace.
Fault Code 19
Reserved.
Fault Code 20
Reason:
The flapper heater current is low.
Primary Action:
Check the Molex connections for the flapper heater.
Secondary Action:
Check the resistance of the heater. If open circuit, replace the heater.
Fault Code 21
Reason:
The flapper heater current is high.
Primary action:
Check for short circuit of the heater. If faulty, replace the heater.
Fault Code 22
Reason:
The resistance of the PC sensor 2 is outside the normal range (> 45K Ohms). PC2
sensor cold.
Primary Action:
Check the connection at the module. Check the resistance of the sensor.
Secondary Action:
Replace the sensor.
Fault Code 23
Reason:
The resistance of the PC sensor 2 is outside the normal range (< 660 Ohms).
PC 2 sensor hot.
Primary Action:
Check the connection of the sensor at the module. Check the resistance of the
sensor.
Secondary Action:
Replace the sensor.
Fault Code 24
Reason:
The resistance of the ice tray sensor is outside the normal range (> 45K Ohms).
Sensor cold.
Primary Action:
Check the connections of the sensor at the module. Check the resistance of the
sensor.
Secondary Action:
Replace the sensor.
Fault Code 25
Reason:
The resistance of the ice tray sensor is outside normal range (< 660 Ohms).
Sensor hot.
Primary Action:
Check the connections of the sensor at the module. Check the resistance of the
sensor.
Secondary Action:
Replace the sensor.
Fault Code 26
Reason:
The icemaker motor timed out.
Primary Action:
The icemaker gearbox is not returning to the start position and ends signal to
controller.
Secondary Action:
Check the gearbox, and if faulty, replace.
Fault Code 27
Reason:
The icemaker motor current is high.
Primary Action:
Check the motor for an obstruction. Check the wiring at both the icemaker
gearbox and the power module.
Secondary Action:
Clear for an obstruction. Test the motor operations. Check the gearbox motor
resistance. If not within limits, replace motor.
Fault Code 28
Reason:
The icemaker solenoid current is high.
Primary Action:
Check the connections to the solenoid. Check the resistance of the solenoid.
Secondary Action:
Correct loose connections. Replace the solenoid if faulty.
