What does Daikin J9 Error Code Mean?

 

Daikin J9 error code simply refers to thermistor error. We commonly tell our technicians that, in A multi split Aircon unit, If only one unit is blinking, It is likely the parts in the indoor unit that are malfunctioning. However, the Daikin j9 error code kind of goes against that. You see, this error code refers to a thermistor malfunctioning in the outdoor unit.

Then why would only 1 indoor unit blink? When the entire outdoor unit pcb controls all indoor units. That is because of some Aircon brands. There are individual thermistors attached to the coil. These thermistors may all be connected to one small plug and all of these thermistors are sold together as one. Hence. If only one of the units has a j9 error code. It is likely the outdoor unit’s part that requires replacement. Furthermore, Daikin has 3 type of thermistors in the outdoor unit. It has liquid, gas and Air thermistors. So the error code matters in determining which type of thermistors require replacement.

As you have read from the previous paragraph. Daikin j9 error code refers to thermistor error. However, other than thermistors, it can also be other Daikin spare parts that are responsible for causing this error. Other than thermistors, the next biggest likely suspect is the pcb.
