What are the reasons for the lack of cooling in the Chery Arrizo 5 air conditioning system?
1 Answers
Chery Arrizo 5 air conditioning system may fail to cool due to the following reasons: 1. Compressor capacitor damage or malfunction: This can cause the compressor to stop working. 2. Room temperature sensor resistance value change: This leads to the outdoor unit not working (the symptom is similar to the air conditioner shutting down after reaching the set temperature). 3. Damage to the indoor or outdoor fan (often due to capacitor failure): Failure of the outdoor fan manifests as excessively high exhaust temperature or high-pressure protection, while failure of the indoor fan results in frost formation on the indoor unit, continuous operation of the outdoor unit, and condensation on the indoor unit. 4. Other factors: Issues such as low power supply voltage reducing the electromagnetic clutch's pull force, or oil contamination between the clutch pressure plate and pulley, can cause a "slipping" phenomenon similar to a loose drive belt. If the evaporator surface frosts over or the blower motor speed decreases, it can also lead to insufficient cooling. Additionally, compressor wear or valve leakage can result in inadequate cooling performance. 5. Refrigeration system issues: Common faults like insufficient cooling or reduced cooling efficiency are often caused by refrigeration system sealing problems. Modern automotive refrigerants have strong permeability, requiring high system sealing standards. Even minor leaks in refrigeration pipelines or valves can cause insufficient cooling.
