    P8 is an outdoor fault code. It could be anything from a thermistor to a faulty contactor. It's not specific, problem is at your outdoor.

    P8 tells you that you have a device active at the outdoor unit and the outdoor has registered the fault ,this does not necessarily mean the fault is with the outdoor unit !
    For example dirty filters can trigger a P8.

    If it has them, check the LEDs of the outdoor unit, they will tell you more.
