Outdoor Heat Exchanger Temperature
Sensor (Outlet) Error
Outdoor Unit Main PCB Circuit
Heat Exchanger Temperature Thermistor
When Heat Exchanger Temperature Thermistor (Outlet) open or
short-circuit is detected at power ON or while running the compressor.
1. Connector connection failure 2.Thermistor failure 3. Main PCB failure
Check Point 1 : Check connection of Connector
Check if connector is removed.
Check erroneous connection.
Check if thermistor cable is open.
>>Upon correcting the removed connector or mis-wiring, reset the power.
Check Point 2 : Remove connector and check Thermistor resistance value
Thermistor Characteristics (Approx. value)
If Thermistor is either open or shorted, replace it and reset the power.
Check Point 3 : Check voltage of Main PCB (DC5.0V)
Make sure circuit diagram of outdoor unit and check terminal voltage at Thermistor (DC5.0V)
If the voltage does not appear, replace Main PCB.
