Trane CNT4958 Pressure Switch

Trane CNT4958 Pressure Switch

The Trane CNT4958 High Pressure Cutout Switch is a critical OEM safety component engineered for HVAC and refrigeration systems to prevent compressor failure due to overpressurization. As a direct replacement for Trane part number X13210096050, this switch provides precise system protection by breaking the electrical circuit when internal pressures reach the 550–650 PSI cutout range. Built to handle dual-voltage applications, the high pressure switch 120/240V configuration ensures versatile compatibility across residential and commercial split systems and rooftop units.

For technicians performing a Trane pressure switch replacement, the CNT4958 features 72-inch lead wires with standard female quarter-inch quick-connect terminals, facilitating a rapid swap-out during service calls. This HVAC high pressure cutout is designed to monitor discharge line pressures, interrupting operation before mechanical damage occurs to the compressor or refrigerant lines. Whether you are troubleshooting a Trane furnace pressure switch error or maintaining a large-capacity industrial chiller, using this genuine Trane replacement part preserves factory-spec safety thresholds and system efficiency.

Key Benefits:

  • Optimized System Safety: Interrupts compressor operation during high-head pressure events to prevent catastrophic hardware failure.
  • Exact OEM Compatibility: Serves as a 100% direct internal replacement for model CNT4958 and X13210096050.
  • Broad Voltage Range: Rated for 120V and 240V, making it suitable for a wide variety of HVACR electrical configurations.
  • Durable Field Performance: Constructed to withstand the high-vibration environment of the compressor compartment.
  • Extended Leads: The included 72-inch wiring harness allows for flexible mounting locations and easier routing through control cabinets.

Common Questions:

How do I test if my Trane pressure switch is bad?
Using a digital multimeter set to continuity, check the terminals while the system is at rest (and pressure is below 550 PSI). The switch should be normally closed. If you read an open circuit under normal pressures, the internal diaphragm or contacts have likely failed, necessitating a replacement.

Will the CNT4958 work as a replacement for the CNT04958?
Yes, the CNT4958 is the same technical specification as the CNT04958. Manufacturers often drop the leading zero on part numbers in their catalogs, but the 550–650 PSI cutout and electrical ratings remain identical.

What causes a high pressure cutout to trip frequently?
Frequent tripping is often indicative of poor heat transfer. Check for dirty condenser coils, a failing outdoor fan motor, or a refrigerant overcharge. If the high-side pressure is verified as normal with gauges but the switch still trips, the switch calibration has drifted and requires replacement.
