1.Checklist :
1) Is the indoor units temperature sensor connected correctly?
2) Is the sensor placed correctly?
3) Does the both terminal of sensor satisfy the resistance value in accordance with temperature?
2. Troubleshooting procedure
Is the sensor resistance value #1-#2
10kohm
±
3% at the room
temperature
of 25
℃
Detach the assembled sensor from the PBA sensor
connector and measure the sensor resistance with
ohmmeter(tester)
Sensor Replace
Sensor resistance value : 20
℃
- 12.09kohm
30
℃
- 8.31kohm
35
℃
- 6.94kohm
40
℃
- 5.83kohm
Below 0.5V or Over 4.5V?
Connect the sensor to PBA connector (4piin)
supply power and measure the voltage of #1-#2 in
the connector
Exchange the indoor PBA
NO
YES
NO
YES
Micom error or connector check
Exchange the indoor PBA
