The pressure switch monitors the differential pressure created by the inducer motor to confirm safe venting conditions before allowing the gas valve to open. When the switch fails — or when it sticks open or closed — the furnace section will lock out, leaving you with no heat despite the inducer running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e LP \/ Propane gas pressure switch | 6.5\" W.C. cut-out setpoint | SPST configuration | Compatible with air, natural gas, and LP gas applications | Mounts horizontally or vertically\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory pressure tolerances. Aftermarket switches often deviate from the rated W.C. setpoint, causing nuisance lockouts or — more dangerously — failing to detect blocked flue conditions. Always use OEM on gas-burning appliances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers. Photograph or label the pressure tubing ports before disconnecting.
