the motor is either defective or disconnected. If neither operates, check the main PCB and
the cabinet wiring.
2. The evaporator fan motor also operates when the PTC heater operates for single zone
models with heat function.
3. To Check The Evaporator Fan Motor,
Disconnect the unit from the source.
Remove the air duct cover.
Disconnect the evaporator fan motor lead connector from the cable.
Connect the motor to a 12V DC power source. If the motor fails to operate, it is defective
and must be replaced.
8.4.4 DETECT THE FAN MOTOR IN THE MIDDLE DIVIDER FOR DUAL ZONE MODELS
(F2C)
1. The fan motor operates independent from the compressor. When the set temperature of
lower zone is not met and lower than the actual storage temperature it operates and at the
rest time it does not run. If the set temperature of lower zone is not met and lower than the
actual storage temperature but the motor doesn't operate, the motor is either defective or
disconnected. If neither operates, check the main PCB and the cabinet wiring.
2. To Check The Fan Motor in Middle Partition,
Disconnect the unit from the source.
Remove the top of middle partition.
Disconnect the fan motor lead connector from the cable.
Connect the motor to a 12V DC power source. If the motor fails to operate, it is defective
and must be replaced.
8.4.5 DETECT THE HEATER FAN MOTOR (F2H)
1. The heater fan motor operates when the PTC heater operates and at the rest time it cycles
ON and OFF to circulate the interior air. If the PTC heater runs but the motor doesn't, the
motor is either defective or disconnected. If neither operates, check the main PCB and the
cabinet wiring.
2. To Check The Heater Fan Motor,
Disconnect the unit from the source.
Remove the bottom air duct cover.
Disconnect the heater fan motor lead connector from the cable.
Connect the motor to a 12V DC power source. If the motor fails to operate, it is defective
and must be replaced.
8.4.6 DETECT THE PTC HEATER
1. The PTC operates when the set temperature is not met and lower than the actual storage
temperature. If not, the PTC heater is either defective or disconnected. If neither operates,
check the main PCB and the cabinet wiring.
2. To Check The PTC Heater,
Disconnect the unit from the source.
