4-3-6 Internal Communication error of the Outdoor Unit C-Box

1. Cause of problem

Replace Main PCB

Restart operation after connecting the Inverter
PCB2 CN31(when the Comp. applied one :
Inverter PCB1) connector. (Check the 3, 4 Pin short)
* Service after turn off the Main Power.

No

Yes

Is the jumper connector connected to CN31 of

Inverter PCB2(when the Comp. applied one :

Inverter PCB1)?

Restart operation after checking the Inverter

PCB2 CN31 and PCB2 CN32 Communication

wire/Connector.(3, 4 Pin Short)

* Service after turn off the Main Power.

No

Yes

Yes

Is Inverter PCB1 CN32 and Inverter PCB2

CN31 connector accurately connected?

1) Check the Inverter PCB1 CN32, CN91 and

Fan PCB CN12 Communication wire/
Connector.

2) Restart operation after connecting the Hub

PCB CN97 and Fan PCB CN13 connector.

* Service after turn off the Main Power.

1) Check the Main PCB : Main PCB TX circuit

inspection

2) Check the Hub PCB : Hub PCB TX circuit

inspection

* Service after turn off the Main Power.

No
