Haier AD28NAAMBEA fault but no code
Chaps,
looking at a Haier ducted split which has been playing up for some time. The previous company diagnosed a faulty compressor but on running it seems fine although the unit stops after a minute of operation on either heating or cooling
There is a hard wired controller but no faults show. The indoor board has flashing lights but seem more random.
One thing I did notice that the outdoor ambient sensor had been chopped and the wired taped together, the actual sensor was missing
I assume the first thing would be to replace the sensor but wonder if anyone has any ideas?

Re: Haier AD28NAAMBEA fault but no code
when it stops is it comp only or cond fan? - might be worth sticking a resitance box or a fixed resistor to trick it to think the ambient is 28deg- which it prob is in your hood, would have thought that the system wouldnt run at all if senssor is linked out

Re: Haier AD28NAAMBEA fault but no code
Found this install manual if of any use, has some fault code info:

and another one here which I'm not sure applies to your model but has all sorts of service info inc. probe resistances:

Other than that not really messed about with Haier.
Heard someone describe them as worse than LG if you could confirm? :-)
Cheers,
Andy.Health and safety first..........unless I'm in a hurry.

Don't suppose it's clever enough to consider frost protection on the evap?
