Daikin mini split issue
Daikin AJ fault
When you get an aftermarket indoor unit PCB you need to get a capacity plug to set the capacity. The factory boards do not have them, so call back wherever you got the board and ask for the appropriate capacity plug.

Hello, I’m having an issue with a Daikin mini split. Was giving me and error code JA when I arrived, which indicates issues related to high pressure. After checking wire connections and making sure outdoor coil is clean I shut off power to indoor and outdoor units for 5 minutes. Once I turned it back on the system eventually started cooling and then, while still calling for cooling, the outdoor fan turned off and liquid pressure went up to 550 psi and the system shut off and gave an error code E3. I went through the same process to watch it do it again and it did the same thing and the code switched back to JA. I’m leaning towards a failed pcb, but not really sure and have not been successful in finding a tech support number. Any thoughts as to what this could be?
