The pressure switch is a critical safety component that monitors negative pressure produced by the inducer motor to confirm proper venting before allowing ignition to proceed. When this switch fails or sticks, the control board will not advance past the inducer stage, resulting in a no-heat lockout condition. Common symptoms include a furnace that starts the inducer fan but shuts down before ignition, along with a pressure switch fault code displayed on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.
