    Carefully check the outdoor unit main printed circuit board and see if Jumper J808 has been cut

    On the remote controller press Test + SET + CL for 4 seconds

    Sroll down to the 'OF' setting and let me know what the Value is.

    Some splits have a small PCB near the interconnect with some DIP switches on which gets corroded.
    Try unplugging this from the main PCB.
    One of those switches selects no heat function which might be your issues. If it is you can just leave it unplugged.

    Cheers,
    Andy.
