This Inverter Mini Split AC PCB Kept Clicking… The Real Fault Shocked Me

This inverter AC outdoor PCB had a nonstop relay clicking problem, burned resistors, voltage fluctuation issues, and possible microcontroller damage. In this video, I diagnose the real fault inside the PCB, test the relays, check the IGBT and capacitors, repair the damaged circuit, and finally get the compressor and outdoor fan motor running again. Three different AC PCBs had the same issue, and all were repaired successfully after tracing the hidden fault causing rapid relay switching and PCB burning. Full inverter AC PCB troubleshooting, relay testing, microcontroller repair, outdoor unit diagnostics, and HVAC electronics repair tutorial step by step. Perfect for technicians, electronics repair learners, and anyone interested in advanced air conditioner PCB repair, relay clicking fault repair, and electronic troubleshooting.
