Reasons for Parking Air Conditioning Not Cooling

[DelCharlie]

Reasons for parking air conditioning not cooling: 1. Unset status: The controller is not set to cooling mode or the set temperature is too high. 2. Insufficient voltage: The main unit cannot start due to insufficient power supply voltage. 3. Poor flare connection: Refrigerant leaks caused by improperly connected flares during installation, or unsealed joints/cracked copper pipes in the pipeline (including potential cracks in the unit's own copper pipes, e.g., at evaporator, condenser, or pipeline connections). 4. Compressor burnout: The main unit's compressor is burned out. Solutions: Contact the purchasing entity for repair/replacement or call the manufacturer.

There may be several common reasons why the parking air conditioner is not cooling. Last time my car had a similar problem, it was caused by insufficient refrigerant due to aging air conditioning pipes leaking Freon. I can first check if the fan is running properly. If the fan doesn't turn, the hot air won't be expelled, and cold air won't come out. A dirty filter is also a big issue, as dust accumulation weakens airflow. Compressor failure would be more troublesome and requires professional equipment to diagnose. Additionally, electrical issues like blown fuses or damaged relays can interrupt power supply. It's recommended to first check the filter and fuse box. If the fan is running but the air isn't cool, it might be a refrigerant issue. Developing a habit of cleaning the filter regularly, every three months, can reduce such failures. If you notice the air conditioner isn't cooling, don't keep running it to avoid overheating and damaging the system. Just drive to a repair shop to get it fixed.

I found that the parking air conditioning not cooling is often related to the compressor and condenser. When the compressor is worn out, it cannot effectively compress the refrigerant, leading to a decrease in cooling efficiency. A clogged condenser or a stuck fan can also significantly reduce the heat dissipation effect. From an electrical perspective, check if the fuse is blown or if there is poor contact in the wiring. Last time, I inspected the relay and found that the contacts were burnt, which caused the power supply to be interrupted. Refrigerant leaks require patching and recharging, which needs professional tools. Occasionally starting the air conditioning can prevent system sluggishness, and parking in a shaded area reduces heat dissipation pressure. Routine maintenance includes cleaning the condenser and checking the sealing of the pipelines, which can save a lot on repair costs.

Parking air conditioning not cooling affects comfort and safety. I noticed it might be due to sensor failure or control module damage. Once it stops cooling, immediately stop to check if the fan and filter are functioning properly. Insufficient refrigerant also wastes energy and causes environmental pollution. Incorrect operation, such as setting the temperature too high, can also make it seem not cool enough. Timely repairs are necessary to avoid fatigue or heatstroke while driving. Maintaining ventilation inside the car and regular maintenance are very important.
