In this video, we tackle a common yet costly mistake with mini split air conditioners: servicing the unit without removing or covering the PCB, which can lead to water damage. After this mishap caused the unit to show an E5 error and shut down, we dive into a detailed step-by-step diagnosis and repair process. Using a multimeter, we test each component, including the fuse, capacitors, shunt resistor, and SMPS, and ultimately find a shorted IGBT that needs replacement. By carefully explaining each testing mode—continuity, resistance, and diode mode—we guide you through identifying and fixing the fault, allowing the AC to operate smoothly again. This video is perfect for DIYers and technicians, offering tips to avoid similar issues by ensuring proper PCB protection during cleaning.
