When we turn aircon on power button flashes twice with the timer button, then just the power button 5 more times. Fan works but no cooling
Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.
Current trip error, if you have had a recent power surge try turning the power off for the unit and back on after a couple of minutes to reset the fault. Sometimes this will work if not it mat have a faulty circuit board

Check that the gas is not leaking, that would be the most likely cause.
