Hi everyone, sorry I haven’t posted for a while.

Please can anyone help me with what seems to be an intermittent problem with a small Haier split. I have been out to it twice – customer says it runs for ’10 minutes’ and then goes off with flashing lights (timer, operation, power). I personally have not seen this. My first visit, the unit ran for 90 minutes in my presence, good as gold. I removed the sound deadening material from the rooftop mounted compressor (it is over 40 degrees here in Cyprus). in case it was a comp overheat problem

Ran Ok for about 4 days, then same problem. I went today and swapped the control PCB from another less important unit on site. Again, I ran both units for 45 minutes and nothing amiss on either of them. Tonight I have the irate customer back telling me it is just the same… I have to go again in the morning. As I said I haven’t seen any of this, but does the flashing lights thing mean anything to anyone hopefully please ? Or any suggestions beyond what I have done ? Many thanks guys
