Question about Cfm Daikin R410a Split System Air Conditioner
Error code c4
C4 error code has nothing to do with outdoor pcb. Use code 41 to check the value of the liquid line sensor and test with mulit meter. Pretty rare fault. Turn the power off for 5
Mins and reboot your system.

it sound like the outdoor pcb has failed, if your unit is less then 5 years old it will be under warranty. if your unit is a rxd50/60/71jvea it will be a fan motor and pcb
