Title
Cause of error
Check point & Normal condition
Check Point
1. Unplug the sensor on Indoor unit PCB.
2. Estimate the resistance of each sensor.
3. If the resistance of the sensor is 10K
Ω
/ 5K
Ω
at 25°C, then sensor is normal.
4. If the resistance of the sensor is 0 K
Ω
or
∞
, then sensor is abnormal.
→
Change the sensor.
5. Plug the sensor on Indoor unit PCB and Power ON.
6. Estimate the voltage of each sensor.
7. If the voltage of the sensor is 2.5Vdc at 25°C, then sensor is normal.
8. If the resistance of the sensor is 0 or 5Vdc, then sensor is abnormal.
→
Repair or Change the PCB.
