A/C Low Pressure Switch for Case New Holland Tractors

Description

When your tractor’s air conditioning suddenly stops working on a sweltering day, the problem’s often hiding in a little switch that most folks never think about. This A/C low pressure switch is designed to protect your compressor from damage by monitoring refrigerant pressure and shutting down the system before it can run in a vacuum—which would destroy expensive internal components and leave you sweating through harvest. Working in the cab on a hot summer day is tough enough without losing your air conditioning.

What You’re Getting

• Threads into the low side of your AC system and wires in series with the compressor clutch coil—when refrigerant pressure drops below the safe threshold, the contacts stay open, cutting power to the compressor
• Built to handle the constant vibration and temperature extremes that come with farm equipment
• Simple electrical connection design that works with existing wiring
• Direct replacement that gets your AC system back to protecting your expensive compressor

Built for Real Farm Work

This pressure switch is designed for agricultural air conditioning systems where reliable cooling makes long days in the field more bearable—whether you’re combining wheat in July heat or baling hay when the humidity’s through the roof, this switch ensures your AC compressor only runs when there’s adequate refrigerant pressure to keep things lubricated and cool. Farm equipment air conditioning takes a beating from dust, vibration, and extreme temperatures.

Made to Last

This switch is built specifically for the harsh environment your tractor works in every day. The electrical contacts are designed to handle the repeated cycling that comes with AC operation, while the housing resists corrosion from moisture and chemicals you might encounter around the farm.

Installation Notes

Installation involves threading the switch into your AC system’s low-pressure port and connecting the electrical leads. Make sure to have your AC system properly evacuated before removing the old switch to avoid losing refrigerant. If your system’s been running low on refrigerant, this switch may have saved your compressor from expensive damage—get the leak fixed and recharged before putting the new switch to work.
