Trane SWT3179 Pressure Switch Kit
For veteran HVAC contractors, the Trane SWT3179 Pressure Switch Kit—which is functionally identical to the SWT03179—is a critical component for restoring furnace ignition sequences. This 0.8" WC setpoint switch is a Single Pole Double Throw (SPDT) configuration, making it highly versatile for monitoring induced draft blower performance and ensuring proper venting before the gas valve opens. Engineering-wise, this OEM replacement part is built for snap-action performance and features standard 1/4" quick-connect terminals, ensuring a precise fit in Trane and American Standard air handlers or furnace units that require a secondary or primary safety circuit feedback. As a technician, you know that a failed diaphragm or oxidized contacts can lead to "pressure switch open" fault codes; this kit allows for a direct-drop replacement to get your client’s inductive draft systems back within factory operating parameters.
Key Benefits for Technicians:- Precise 0.8" WC Calibration: Directly matches factory setpoints for draft inducer safety protocols.
- SPDT Contact Versatility: Supports both normally open (NO) and normally closed (NC) wiring configurations common in modern control boards.
- Cross-Compatibility: Confirmed 1:1 replacement for SWT03179, reducing inventory confusion.
- Durable Construction: Engineered with a high-grade diaphragm and rapid-trip mechanism for consistent cycling.
Is the SWT3179 a direct replacement for SWT03179?
Yes, the two part numbers represent the same technical specification and are interchangeable in all furnace and air handler applications.
What causes a pressure switch fault if the switch is new?
Before assuming a defective part, check for restricted flue pipes, a failing inducer motor, or cracked silicone tubing that could prevent the diaphragm from sensing the required 0.8" water column pressure.
How do I test the SPDT terminals?
Use a multimeter to verify continuity across the common and normally closed terminals at rest, and across common and normally open once the inducer creates sufficient vacuum.
