GPD 1711502 A/C Clutch Cycling Switch

The GPD 1711502 A/C Clutch Cycling Switch is a critical component designed to regulate air conditioning compressor operation by monitoring low-side refrigerant pressure. This electrical switch provides feedback to the vehicle's engine management system, cycling the compressor clutch on and off to maintain optimal evaporator temperature and prevent system damage.

Key Features:

• Designed to meet or exceed OE fit, form, and function specifications
• Voltage tested and amperage draw tested for reliable performance
• Durability tested on every new design to ensure long service life
• Typically mounts on the accumulator near the evaporator outlet
• Prevents evaporator freeze-up by maintaining proper temperature range
• Protects compressor from damage due to low refrigerant levels

This switch acts as a transducer, changing internal resistance in response to pressure changes in the A/C system. When pressure drops below a safe threshold, the switch deactivates the compressor clutch to prevent operation without adequate lubrication. Once proper pressure is restored, the switch allows normal clutch engagement and compressor operation. The GPD 1711502 is engineered for fixed orifice tube (CCOT) A/C systems and includes a 12-month warranty.
