Low refrigerant, a dirty condenser, fan failure, moisture, blockages and mechanical faults behind poor AC cooling — plus the MSG MS111 test bench.
When a car’s air conditioner fails to cool the cabin properly, MSG Equipment says the cause is usually one of six faults:
- Low refrigerant level
- A dirty condenser
- Condenser fan failure
- Air or moisture in the system
- Rust, sand or debris clogging orifice tubes and valves
- Compressor wear, or clutch, valve or pressure sensor failure
Professional workshop help is recommended for diagnosis and repair. The MSG MS111 test bench enables fast, reliable checks of R134a compressors and AC systems, with LCD control, automatic evacuation and storage of test results.
