Analysis and Maintenance: The machine malfunctioned just 10 days after installation. When powered on for testing, the light board displayed normally, and the outdoor unit worked for a few minutes before stopping. Measured with a multimeter, the supply voltage was normal. Using a pressure gauge to measure the low-pressure pressure in the system, the low pressure was normal when the outdoor unit started, but then the pressure gradually decreased. It was analyzed that it might be due to insufficient return gas, causing the compressor temperature to rise too high and stop. Careful observation revealed frost formation on the capillary tube. Therefore, it was determined that there was ice or dirt blockage in the system. After re-evacuating, drying, and adding fluoride, the machine was tested again and everything returned to normal.
