Why does the Mercedes-Benz air conditioning not cool after exposure to sunlight?

[DeWeston]

The following is a related introduction about the Mercedes-Benz air conditioning not cooling after exposure to sunlight: 1. The phenomenon of compressor protection device tripping: Overload protection of the compressor will trip, indicating that the system's high-pressure is too high or the current is too large. Excessive refrigerant. Appropriately reduce the refrigerant amount. Poor heat dissipation. Check if the condenser pipe is dirty and clean the condenser. Blockage in the pipeline system. Refer to the pressure gauge for judgment, troubleshooting, and re-system processing. Dust and scale accumulation on the evaporator or filter. Reduced airflow, imbalance in system pressure and temperature, clean the evaporator or filter. Lack of refrigerant is also possible. When refrigerant is lacking, the compressor's exhaust temperature will overheat, causing the overload protection switch to trip. 2. Electrical aspects: Control circuit board failure. Temperature sensor overload, incorrect information. Loose or poor contact in power wiring. The starting capacitor or compressor starting coil is burned out.
