9.4.2.4E4(open or short circuit of outdoor temperature sensor) diagnosis and solution
F1/F2/F3/F4/F5 (open or short circuit of indoor coil temperature sensor) diagnosis and solution.
.
Error Code
E4/F1/F2/F3/F4/F5
Malfunction decision
conditions
If the sampling voltage is lower than 0.06V or higher than
4.94V, the LED will display the failure.
Supposed causes
●
Wiring mistake
●
Sensor faulty
●
PCB faulty
Trouble shooting:
Check the connections
between temperature
sensor and PCB. Are
the connections good?
Correct the connections.
No
Yes
Yes
Replace indoor or outdoor PCB.
Replace the sensor
Check the resistance value
of the sensor via Appendix 1
and Appendix 2
Is it normal?
No
