FORD R12 CYC PRESS SW - FJC

The FJC 3214 Compressor Clutch Cycling Pressure Switch is an essential component designed for maintaining the optimal performance and longevity of R-12 automotive air conditioning systems. This professional-grade switch accurately monitors the low-side refrigerant pressure, ensuring the A/C compressor cycles correctly to prevent evaporator freeze-up and protect the compressor from damage due to insufficient refrigerant levels.

Key Features

• R-12 System Specific: Engineered exclusively for vehicles utilizing R-12 refrigerant systems, ensuring precise operation and compatibility.
• Compressor Protection: Safeguards the A/C compressor by preventing it from running under dangerously low refrigerant conditions, which can lead to costly component failure.
• Evaporator Freeze Prevention: Regulates compressor cycling to maintain evaporator temperature above freezing, optimizing cooling efficiency and preventing airflow blockage.
• Accurate Pressure Control: Activates the compressor around 45 PSI and deactivates it around 25 PSI, promoting consistent system operation.
• Durable Construction: Features a weatherproof sealed design for reliable performance in demanding automotive environments.
• Direct Replacement: Provides a high-quality, professional-grade replacement for original equipment, facilitating straightforward installation.

Applications

This FJC 3214 cycling pressure switch is specifically applicable to a range of Ford vehicles manufactured approximately between 1980 and 1993 that came equipped with R-12 air conditioning systems. It is also compatible with certain Lincoln, Mazda, Mercury, Merkur, and Nissan/Datsun models from similar production years. Ideal for professional technicians and mechanics working on vintage or classic vehicles requiring precise R-12 A/C system maintenance and repair, ensuring proper function of the low-pressure side of the A/C circuit.
