- In this video, I troubleshot and repaired a Haier DC inverter mini split air conditioner PCB that had a persistent short circuit. The PCB worked for a while but then shut down the compressor, and the root cause was hidden in the SMPS section. After checking the 5V voltage regulator, which overheated to 73°C, I replaced it but the problem remained. Upon further inspection, I discovered that the operational amplifier and two resistors were faulty. Watch as I walk you through the step-by-step repair process, explain the role of these components, and bring the AC back to life! If you're facing issues with your Haier inverter AC, like the compressor stopping unexpectedly, this video will help you understand common PCB failures and how to fix them. Whether you're a technician or a DIY enthusiast, this tutorial is perfect for learning how to diagnose and repair SMPS-related faults in inverter air conditioners.
