Description: When the outdoor fan speed is to low or to high undeterminate amount of time, the LED displays the
failure code and the system turns off.
2. Outdoor DC Fan Motor (control chip
is integrated on the PCB:
Power on the system and place the unit in standby mode. Measure the
voltage between pin 1 and pin 3, pin 4 and pin 4 on the fan motor connector.
If the value of the voltage is not in the range showing in the below table, the
outdoor PCB must issues and will need to be replaced.
4.6. TS05-IDU
Description: Open circuit or short circuit of indoor temperature sensors (T1 or T2). If the sampling voltage is lower than
0.06V or higher than 4.94V, the LED displays the failure code.
Possible Affected Components: Indoor main PCB, sensors or connection wires.
Troubleshooting and Repair:
This illustration and the value displayed is only an exampled and actual appearance and value may vary.
