Fault Code 15
Reason: The PC fan is drawing less current than is expected. Either the wiring is open circuit
or the fan is faulty.
Primary Action: Check the PC fan wiring and connections at both the fan and the power module.
Secondary Action: Check the fan. If faulty, replace.
Fault Code 16
Reason: The PC fan is drawing more current than is expected. Either the wiring is shorted or
the fan is faulty.
Primary Action: Check the PC fan wiring and connections at both the fan and the power module.
Secondary Action: Check the fan. If faulty, replace.
Fault Code 17
Reason: The FC fan is drawing less current than is expected. Either the wiring is open circuit
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 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: Flapper heater current 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.

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.
