The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or its hose collapses, the control board detects an open circuit and locks out the furnace — resulting in a no-heat call with a pressure switch fault code. Two OEM part numbers are available: \u003cstrong\u003eHK06WC085\u003c\/strong\u003e (standard pressure switch) and \u003cstrong\u003eHK06WC097\u003c\/strong\u003e (pressure switch with mounting bracket). Select the variant that matches your existing configuration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Factory water column (W.C.) rating matched to GA1AAD060100ABJA inducer assembly | SPST normally-open configuration | Rated for single-stage gas furnace operation | Includes rubber sensing hose port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are calibrated to the exact W.C. trip point specified by Carrier engineering.
