3. Defect of outdoor PCB

Check Point

1. Estimate the resistance of each sensor.(Unplugged)

2. Check the value of the resistor of thermistor.

D-pipe sensor (Inverter) : Normal Value of the resistor is 200kΩ at 25℃

Air sensor : Normal Value of the resistor is 10kΩ at 25℃

Cond. Mid-pipe sensor : Normal Value of the resistor is 5kΩ at 25℃

Suction pipe sensor : Normal Value of the resistor is 5kΩ at 25℃

Condenser Out-pipe sensor : Normal Value of the resistor is 5kΩ at 25℃

Is sensor connected

to PCB correctly??

Is sensor value correct?*

Connect sensor to PCB correctly

Replace sensor

Replace corresponding

outdoor unit PCB

Yes
