An A/C pressure switch is a monitoring device mounted on the upper and lower sides of air conditioning systems. Based on the level of refrigerant pressure detected by the switch, the system's compressor is automatically turned on or off to prevent damage.
Importance of A/C Pressure Switch
The AC pressure switch in a car is a vital component of the vehicle’s air conditioning system. It is important to ensure that the switch is in proper working condition for effective monitoring and regulation of AC pressure. The pressure switch acts as a safety device by enabling or disabling the car compressor whenever required to avoid potential damage.
A compact device with a simple mechanism, the pressure switch shuts down the AC compressor in the event of two pressure thresholds. Too high pressure can lead to compressor overheating, while extremely low-pressure levels lead to inadequate lubrication of the air conditioning system. Both these scenarios can cause system damage or failure that will incur extensive repair costs. Thus, the A/C pressure switch plays an important role in preventing the occurrence of any such situation.
How Does A/C Pressure Switch Work?
Each air conditioning system has two such pressure switches- the AC low-pressure switch and the AC high-pressure switch for efficient management of refrigerant pressure. Here’s how these two switches work in tandem to regulate the temperature of the car through its AC system:
- Monitors pressure level of the A/C loop
Detects low-pressure levels possibly caused by a leak, prevents them from falling further, and thus protects the system’s compressor.
Detects high-pressure levels arising due to blockage issues and prevents further increase, thereby preventing complete shutdown
Conclusion
Proper vehicle functioning necessitates maintaining each of its individual parts, including the A/C pressure switch. Vehicle maintenance and repair due to damage can be costly. Hence, it is recommended to buy a car insurance plan and add-ons that provide coverage for all your needs.
