What Causes No Cold Air from the Air Conditioner?
1 Answers
The reasons for no cold air from the air conditioner are: 1. Refrigerant leakage; 2. Damaged or faulty compressor capacitor, causing the compressor to not work; 3. Four-way valve or compressor high-low pressure gas mixing, the air conditioner works but has no effect; 4. Faulty control board of the indoor or outdoor unit leading to no cooling; 5. Damaged indoor or outdoor fan; 6. Insufficient cooling due to too much or too little refrigerant. Cleaning the car air conditioner plays a significant role in addressing the issue of no cooling. Most cases of no cooling are due to long-term lack of cleaning. The condenser of the air conditioner, which is the outdoor heat exchanger, directly forces heat exchange between the refrigerant inside the tubes and the air outside, thereby achieving the purpose of cooling the air. Excessive dust on the condenser, if not cleaned in time, will accumulate and worsen, leading to poor heat dissipation and reduced cooling efficiency.
