Trane SWT2515 Pressure Switch

The Trane SWT2515 is a high-precision HVAC pressure switch calibrated to a 1.36" WC setpoint for critical safety monitoring in gas furnaces and air handlers. This SPST (Single Pole Single Throw) air pressure sensor acts as a primary safety interlock, ensuring the draft inducer motor generates sufficient negative pressure before the ignition sequence begins. Designed for maximum reliability in high-cycle environments, the SWT2515 provides a 1/4" barb connection for a secure vacuum hose fitment, preventing typical air leaks that trigger nuisance "pressure switch open" error codes.

As a direct OEM replacement for the C341825P04 and the discontinued SWT02515, this component maintains strict compliance with manufacturer specs. For field technicians, it serves as a drop-in solution for American Standard and Trane equipment where venting integrity or flue obstructions must be monitored. The robust internal diaphragm is engineered to withstand long-term exposure to combustion byproducts, ensuring consistent electrical continuity during every heating demand. When you encounter a furnace pressure switch error, installing a genuine Trane SWT2515 is the industry-standard method to restore system safety and operational performance.

• OEM Compatibility: Exact replacement for Trane C341825P04, ensuring no modification to mounting brackets or wiring is required.
• Precise 1.36" WC Trip Point: Factory-calibrated for accurate combustion airflow monitoring to prevent unsafe firing conditions.
• Standardized Connections: Features 1/4" barb ports and 1/4" quick-connect terminals for rapid job site installation.
• Heavy-Duty Construction: Built to endure the high-temperature conditions of a furnace cabinet while maintaining SPST switch integrity.

• Will this fix a 3-flash or 2-flash "Pressure Switch Open" error? If your inducer motor is running but the control board isn't seeing the circuit close, the SWT2515 is a likely culprit—assuming the flue and vacuum hoses are clear of debris.
• Is this switch compatible with American Standard furnaces? Yes, since Trane and American Standard share the same parts catalog, this is the correct exhaust pressure switch for units requiring a 1.36" WC rating.
• Can I use a universal adjustable switch instead? For safety-critical venting protection, it is highly recommended to use the fixed OEM SWT2515 to ensure the system trips at the exact pressure mandated by the design.
