  15. My Samsung split AC unit with model No: AR18HCFQAWKN has been shutting off intermittently with error code “EC”. This strange error is not listed among the error codes you have listed. When this error appears the remote is rendered inoperative and I have to turn it off and on by the mains to restart it.
    Could you therefore help with this.

  16. I have a Samsung split system that turns on for a few minutes then turns off with LED’s flashing on the indoor unit on the running and turbo indicator lights.
    Model number is AQV18NSBN

    I have tried resetting via the circuit breaker but the problem persists.

  17. Samsung AR24 error code E465/E500
    The Outside board was replaced by agents 2 months ago.
    It looked like the compressor ic had overheated judging by the colour of the copper plate that goes against the heatsink.
    The unit is now giving the same fault code as it was before the outside pc board packed up the last time.
    Can you give me some advice as what to look for or what could be the issue.
