The pressure switch is a critical safety component that monitors negative pressure created by the induced draft blower, confirming proper venting before allowing ignition to proceed. When this switch fails — or when its hose, port, or diaphragm degrades — the control board never receives the \"inducer proven\" signal, resulting in a no-heat lockout condition. Symptoms typically include the inducer motor running continuously with no ignition attempt, or a fault code indicating a pressure switch error on the board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched water column (W.C.) trip point | Single-port diaphragm-style switch | 24V control circuit compatible | Factory-calibrated for correct inducer pressure range on the CP48P548P509011CP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, factory-calibrated to the exact W.C. rating required by the CP48P548P509011CP.
