So the transformer out on the pole blew yesterday, and after supplying low voltage, dirty power for about 5 hours PEA finally fixed the problem. Unfortunately, my expensive Haier Inverter Air Conditioner did not handle the power spikes well, and now flashes F12 at me when I try and turn it on.

A quick glance through the service manual says replace the PCB in the outdoor unit. Yuk. Sounds expensive.

I really loathe the thought of calling one of these criminals, I mean, repairman to come out and charge me 3x what the part is worth. Does anyone know if it is possible to buy a spare PCB somewhere? I'm in northern Bangkok, but ordering on line is always an option. Luckily, the weather isn't punishing right now, so I can afford to wait a few days to resolve this problem, but I really need to get this corrected.

Any thoughts on how I can do this myself?

Thanks

Have you tried switching off the power for the AC at the main circuit breaker and left off for five minutes. Sometimes they have false alarms and this will reset it.


Cheers

Try contacting Haier Thailand, they may (or may not) sell service spares direct http://www.haier.com/th/

 

You will need the EXACT part number of the dead board, whilst you're at it Google that part number, Ebay may be your friend.

 

But, it's worth remembering that my experience with Samsung is that the parts on Ebay were actually more expensive than paying the genuine Samsung man to come out and fix the beast.

you could try a company named AMORN  they have outlets all over   google or facebook

Amorn may actually be able to fix the fried one. Have a chat with them.
