I've been, troubleshooting/fixing, a few MXZ-A26WV multi-split misubishi units.
I've had the same issues since beggining. These units are installed near sea, they are exposed to high velocity winds, sea salt, rain etc.
My main problem is that the Power Board, Noise Filter and sometimes Electronic PCBoard are always geting themselves defective. It usually starts with PFC defective due to overcurrent (altough I'venever been able to read any overcurrent issue), and it "spreads" to the other boards.
I was thinking that this could be possibly due to wind gusts that produce some voltage on the fan motor and it damages the PFC circuit, dou any of you think it's possible?
Also oxidation has been an issue, the lev coils have o be constantly replaced.
Any help on this, would be appretiated...
