First PCB Repair Failed — Full AC Troubleshooting Process

This AC repair looked simple at first… but the problem was much deeper than expected. I repaired the AC PCB and thought the unit would start working normally again, but the air conditioner still had faults and communication problems between the indoor and outdoor unit. In this full split AC repair video, I show the complete troubleshooting process step by step using a multimeter, voltage testing, PCB diagnosis, and signal checking methods used by professional AC technicians. During this air conditioner PCB repair, I checked DC voltage, indoor outdoor communication signals, relays, outdoor PCB components, and control board circuits to find the real issue. The first PCB repair failed, so I continued the AC troubleshooting process until the exact fault was discovered. This video includes practical testing methods for inverter AC PCB repair, non inverter AC repair, air conditioner outdoor unit repair, and electronic PCB repair techniques. If you want to learn AC fault finding, HVAC repair, universal PCB repair, compressor troubleshooting, electrical troubleshooting, and air conditioner diagnosis, this video will help you understand how real technicians repair difficult AC problems in the workshop and in the field.
