Protect your air conditioning system with this normally closed high pressure switch for John Deere® tractors. Calibrated specifically for use with R-134a refrigerant, this switch ensures proper cut-off and restart pressures for modern A/C systems. It opens at 375 PSI to interrupt power to the compressor when system pressures get too high, then closes again at 190 PSI to restore normal operation.
Compatible with most John Deere® tractor models, this replacement part meets OEM specifications for reliable fit and performance. Using a switch matched to your refrigerant type helps maintain safe operation, prevents component damage, and ensures efficient cooling during heavy fieldwork or extreme heat.
As a best practice, always replace the high pressure switch when retrofitting or servicing your A/C system. This ensures proper calibration, safe system pressures, and long-term reliability.
