What causes the frequent burnout of the air conditioning pressure switch in the new Santana?
2 Answers
It may be caused by excessive resistance leading to the frequent burnout of the pressure switch. The air conditioning pressure switch in a car is an indispensable control component that ensures the normal operation of the car's air conditioning refrigeration system. Pressure control can be categorized into high, medium, and low levels; furthermore, there are distinctions between 2, 3, and 4-wire configurations. Below is extended information on air conditioning pressure: Pressure Temperature Sensor: Refers to a sensor capable of detecting temperature and converting it into an usable output signal. Temperature sensors are the core components of temperature measurement instruments and come in a wide variety. Based on measurement methods, they can be divided into contact and non-contact types, and according to sensor materials and electronic component characteristics, they are classified into thermal resistors and thermocouples. Loss of Protection Function: If the high-pressure switch loses its protective function, the system may experience issues such as pipe bursts, belt slippage, and engine stalling. If the low-pressure switch fails, in the event of a system leak, foreign objects or water may enter the system, causing irreversible damage to the refrigeration system.
I often encounter the issue of the New Santana's air conditioning pressure switch burning out, which is quite common. Most of the time, it's due to a problem in the refrigeration system, such as refrigerant leakage or overcharging. When the pressure becomes abnormal, the switch can't handle it and burns out. Alternatively, it could be an electrical issue—from what I've observed, high voltage or a short circuit can also cause it to burn. High summer temperatures, poor heat dissipation, or a low-quality switch that isn't installed tightly can also lead to this problem. I recommend regularly checking the air conditioning lines for leaks and avoiding overloading the system, as repairs can be time-consuming and costly. If the issue persists, it's best to visit a professional shop to test the voltage and pressure to prevent breakdowns on the road. Taking these preventive measures saves both money and hassle.
