Description
The Trane CNT10426 is an OEM replacement pressure switch designed to maintain safe and reliable operation in Trane heating and HVAC systems. Calibrated to a setpoint of 0.10 inches water column (IN WC) in a normally open configuration, this switch monitors draft pressure within the system and signals the control board only when the correct pressure conditions are met — helping to prevent unsafe ignition sequences.
How It Works
Pressure switches are critical safety components in gas furnaces and air handlers. The CNT10426 monitors the negative pressure created by the inducer motor. If adequate draft pressure is not detected, the switch remains open, interrupting the ignition sequence and protecting the heat exchanger and combustion system from damage.

Application
The CNT10426 is intended for use in compatible Trane furnaces and HVAC systems requiring a 0.10 IN WC normally open pressure switch. Always verify compatibility with your specific unit model before installation.
Why Choose OEM Trane Parts?
Using genuine Trane OEM replacement components ensures proper fit, function, and system reliability. Aftermarket substitutes may not meet the precise calibration requirements of your Trane equipment.
