The pressure switch proves that the inducer motor has established proper draft before allowing the ignition sequence to proceed. When the diaphragm fails or the switch sticks open, the control board detects a pressure fault and locks out the furnace — typically displaying an error code before any heat is produced. Replacing this switch with the correct OEM part restores safe, reliable furnace operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole, Single-Throw) | Set point: -1.65\" W.C. | Rated 1.81\" WC | 1\/4\" barbed hose connection | Includes factory mounting bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Carrier part is factory-calibrated to the exact W.C. rating required by the PG9MAB048080LBSA.
