Description
The Armstrong Furnace R101432-16 is an OEM replacement pressure switch engineered for precise draft and pressure monitoring in Armstrong furnace systems. With a calibrated set point of -0.55″ water column (wc), this single-pole single-throw (SPST) switch accurately detects inducer operation and proper venting conditions, helping to protect the heat exchanger and ensure safe furnace operation.
Key Features
- OEM Armstrong Furnace replacement part — SKU R101432-16
- Rated set point: -0.55″ water column (wc)
- Single-pole single-throw (SPST) switching action
- Dual 1/4″ barb port connections for easy hose attachment
- Monitors inducer blower performance and venting integrity
- Designed to shut down burner operation if unsafe pressure conditions are detected
- Direct OEM fit for compatible Armstrong furnace models
How It Works
The pressure switch senses negative pressure generated by the draft inducer motor. When the inducer creates the correct level of negative pressure, the switch closes, signaling the control board to proceed with ignition. If the pressure falls outside the acceptable range — indicating a blocked flue, failed inducer, or cracked heat exchanger — the switch remains open, preventing the furnace from firing and protecting occupants from potential hazards.
Application
- Direct replacement for Armstrong Furnace systems requiring the R101432-16 pressure switch
- Compatible with gas furnaces utilizing induced-draft or condensing combustion systems
- Dual 1/4″ barb ports accommodate standard rubber pressure tubing for straightforward installation
Why Choose an OEM Pressure Switch?
Using a genuine OEM pressure switch ensures the correct set point calibration for your specific furnace model. An improperly rated switch can cause nuisance lockouts or, more critically, allow the furnace to operate under unsafe conditions. The Armstrong Furnace R101432-16 delivers the factory-specified performance your system demands.
