I have two Pioneer mini splits in my house, and so far have been very happy with them. But as we hit record temperatures one of them quit of course.
I did a diagnosis and the likely culprit is the main control board in the outdoor unit. I've e-mailed HighSeer and Parker Davis to try and get a replacement, but so far no reply.
Does anyone know who really makes these units as they are sold as both Mr. Cool and Pioneer.
If I can find out the real manufacturer and how many other makes it has been rebadged to I have a better chance of finding replacement parts.
Alternatively does anyone have a full schematic of the control board so I can trace the fault at the component level.
