What is the reason for the noise when the Baojun 730 air conditioner is turned on?
2 Answers
It may be the sound of the air conditioning compressor electromagnetic clutch engaging, which is normal. It could also indicate an issue with the air conditioning system. Reasons for clutch noise: When the cooling reaches the set temperature or the air conditioning pipeline pressure is too high, the compressor electromagnetic clutch will automatically disengage, and the compressor pulley will idle. When cooling is needed again, the compressor electromagnetic clutch will engage, producing noise during engagement. Air conditioning problem solutions: Adjust the internal pressure of the air conditioning pipeline, adjust the tightness of the air conditioning belt, and regulate the refrigerant dosage. It is advisable to visit a 4S store or a professional auto repair shop promptly.
As a car mechanic, I've seen many Baojun 730 models with AC noise issues. The most common causes are worn compressor bearings or loose belts, which create squeaky sounds when running, especially noticeable when using AC in summer. Another possibility is dust-clogged condenser fans causing motor humming noises that intensify on bumpy roads. For diagnosis: first check belt tension by hand-pulling, then locate the noise source - compressors usually make clicking sounds while fans produce whirring noises. Address minor issues promptly - replacing belts or cleaning fan blades costs little, but delaying until compressor failure leads to expensive repairs. Regular maintenance is key: clean AC systems periodically and inspect belt wear every six months.
