Fujitsu Mini Split A/C Circuit Board Not Turning On Test

[@kerimyigit5370]

Hello master, thank you for your teaching! I am HVAC teacher in Turkey, I show and recommend your videos to my students. I advise my students to stay away from PCB-controlled devices. Because PCB-controlled devices are much more likely to malfunction than mechanically controlled devices. However, cost economies force companies to produce devices controlled by PCBs with lots of complex circuits. While PCBs are cheap for the company producing the device, they can be a complete nuisance for the consumer.

Wow Impressive Sir 👏👏👏 the knowledge & experience you have on pcb's & circuits, hope i could learn some.youtube is supposed to have more contents like this. But it has all the nonsense from tiktok and Instagram.

[@forevertechenglish]

Thanks For that, Sir.

[@forevertechenglish]

It is due to the surge in short form content, people have short attention span now.

[@SanelKeys]

So, instead of repair, you broke it?

[@forevertechenglish]

I didn't broke it, I tested it, but at the end micro controller is damaged, so working on this board is useless. Every part of the board is available in market not the micro controller, untill you find one from the same board. Which has some other problem in it
