Description
The Amana / Goodman 20197311 is a factory‑original SPST furnace air pressure switch, calibrated to ‑0.60″ water column (WC). This vital control component ensures safe furnace operation by verifying that the inducer motor is creating sufficient vacuum before allowing the ignition sequence to proceed.
Features:
- OEM Quality & Fit: This is a genuine Goodman / Amana pressure switch—designed to original equipment specs for reliable compatibility and performance.
- Accurate –0.60″ WC Calibration: The 20197311 model trips at approximately –0.60 inches of water column, making it ideal for many high‑efficiency gas furnaces requiring solid inducer vacuum proofing.
- SPST (Single Pole, Single Throw) Switch: Designed with a straightforward SPST design, it activates (closes) when vacuum reaches the switch threshold, enabling the control board to move on to ignition.
- Standard ¼‑in Barb Connection: Fits standard vacuum tubing with a ¼‑inch barb fitting, simplifying hookup and replacement in most furnace inducer assemblies.
- Robust Construction: Designed to withstand the rigors of HVAC environments—temperature changes, vibration, and pressure cycling—ensuring long life and reliable function.
