Room temperature thermistor
When Room temperature thermistor open or short-circuit is detected.
1. Connector connection failure 2.Thermistor failure 3. Controller PCB failure
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.
Thermistor Characteristics (Approx. value)
If Thermistor is either open or shorted, replace it and reset the power.
Make sure circuit diagram of indoor unit and check terminal voltage at Thermistor (DC5.0V)
If the voltage does not appear, replace Controller PCB.
