What are the causes of damage to a car's evaporator?
2 Answers
Here are the reasons for damage to a car's evaporator: 1. Blower temperature: The blower temperature is set too low, causing the evaporator to accumulate too much ice before it can evaporate the existing ice. 2. Insensitive temperature sensor: The evaporator's temperature sensor is not sensitive enough, resulting in no signal being sent to stop the compressor, leading to icing. 3. Loud noise: Since the desired temperature is never reached, the compressor operates at full load continuously, which can shorten its lifespan. 4. Water leakage: If the car's evaporator is damaged, water from the throttle valve will leak out.
I've encountered evaporator damage several times, mainly due to driving habits. For instance, I often drive in rural areas where vibrations on bumpy roads are severe. Over time, aging components become loose, leading to refrigerant leaks or cracks at connection points. Another common cause is foreign object blockage. Once, I found the fan completely clogged with leaves and dust, rendering the cooling system ineffective, and it had to be disassembled for cleaning. Regularly cleaning the AC filter is crucial—I recommend doing it at least every six months, especially after driving in dusty environments. Additionally, chemical corrosion is another factor. If the refrigerant is improper or the weather is humid, metal components are prone to rust. Nowadays, during maintenance, I always remind the mechanic to inspect this part, which helps avoid many issues. Paying attention to details never hurts.
