Armstrong Furnace R101432-16 Pressure Switch

When the job requires a precise match for Armstrong Air or Allied Air heating units, the Armstrong Furnace R101432-13 Pressure Switch is the mandatory OEM replacement for ensuring safe combustion. This -.55"wc SPST pressure switch is engineered to monitor the negative pressure generated by the inducer motor, verifying a clear flue and adequate draft before the ignition sequence begins. Featuring dual 1/4" barb connections, this switch provides a secure, leak-free seat for sensing hoses, preventing the nuisance lockouts commonly caused by poorly seated or cracked furnace pressure tubing. Designed for long-term reliability in high-cycle environments, this direct replacement pressure switch ensures your client's system remains operational and compliant with factory safety standards.

• OEM Specified Precision: Factory-calibrated to a -.55" WC set point for exact furnace pressure switch compatibility with Armstrong equipment.
• Enhanced Durability: Robust SPST (Single Pole Single Throw) internal contacts designed to withstand thousands of heating cycles without pitting or sticking.
• Simplified Installation: Standard dual 1/4" barb configuration allows for rapid swap-outs in the field, reducing labor time on service calls.
• Reliable Safety Interface: Prevents gas valve initiation if restricted venting or a failing inducer motor is detected, protecting the heat exchanger.

What causes a pressure switch stuck open error?
Technicians should first verify that the inducer motor is reaching full RPM and check the flue pipe for obstructions such as bird nests or ice. If the venting is clear and the sensing hose is free of cracks or moisture, the R101432-16 switch diaphragm may be ruptured, necessitating a replacement.

Can I use a universal switch instead of the R101432-16?
While universal switches exist, they often require manual calibration. Using this OEM Armstrong pressure switch ensures the safety circuit operates exactly at the -.55" WC threshold, eliminating the risk of late-season failures due to incorrect set points.
