Description
When your tractor’s A/C starts acting up or stops cooling altogether, this little switch might be the culprit. Working cab air conditioning isn’t just about comfort – it keeps you alert and focused during those long summer days of cultivation, harvesting, or custom work. This low pressure switch mounts right on your drier and monitors refrigerant pressure, shutting down the compressor when levels drop to prevent expensive damage.
What You’re Getting
- Opens at 30 PSI to protect your compressor from running without proper refrigerant flow
- Closes at 30 PSI to restart the system once pressure is restored
- Normally open design means the circuit stays open when pressure drops
- Drier mount configuration fits directly on your air conditioning receiver drier
- Built to handle the vibration and temperature swings of tractor operation
Built for Real Farm Work
This switch is designed specifically for Case IH’s heavy-duty 4366, 4568, and 4586 tractors – machines that typically see long hours in demanding conditions. Whether you’re running a 4366 with a disc harrow, pushing a 4568 through harvest with a grain head, or pulling heavy tillage equipment with a 4586, reliable A/C keeps you productive when the heat gets brutal.
Made to Last
The switch housing is built to withstand engine compartment heat, road salt, and crop chemicals that can corrode lesser components. Quality contacts ensure reliable switching action even after thousands of cycles, while the threaded connection provides a leak-tight seal on your drier.
Good to Know
This switch threads directly into your A/C receiver drier – no modifications needed. If your A/C isn’t cooling and the compressor won’t engage, check this switch first before assuming you need expensive compressor work. A simple continuity test with a multimeter will tell you if it’s working properly. When replacing, make sure your system has proper refrigerant levels or the new switch will just shut down the compressor again.
