Hi, I have to see a split hitachi 3200f the problem that is doing is that it works normally but after a while all internal and external fan compressor stops only the diplay lights are shown ... someone can tell me if it is the platelet and if that's how it could be failing .. thanks

it is an inverter system, outdoor unit sensors, or in some cases ignored, the physical ground is failing

I go through the spout sensor, to make a test, remove the spout sensor from its place, let it loose and start the equipment if it does not stop or does not produce the fault, it is the sensor, replace. Luck.

I should try separately. Separate indoor unit from outdoor. and give tension, that way you will see if the platelet still behaves the same. Luck
