Analysis and repair; During the power-on inspection, it was found that the compressor temperature was relatively high, the current was lower than normal, at only around 3A. The low-pressure pressure was also at 0.3MPa, while the external fan was operating normally. It was suspected that there might be a leak in the air conditioner refrigeration system or poor suction and exhaust performance of the compressor. A system leakage test was conducted, revealing a slight leak at the welding point of the U-shaped end of the condenser. After re-welding, the vacuum was drawn, Freon was added, and upon restarting the unit, the air conditioner returned to normal operation.
