Hmmmm.... Many home made experts talking a lot.. the different between you and them is that you do not talk more then it needs and knowing what you are talking about...(-: (-; GREAT!!!
If one out of 4 indoor units in an LG multi-head system is not heating, what could its EEV be doing? Stuck open or closed or partially open or partially closed?
What are the common issues with the rusted power heads? Other then fujitus bad eev coils shorting out (current model), ive never had issues. So im curious as to what to look out in the future
