The pressure switch is a critical safety component that monitors the negative pressure (inches water column) created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails — or when it is tripped by a blocked flue, failed inducer, or cracked diaphragm — the control board halts the heating cycle entirely, resulting in a no-heat condition with the system stuck in pre-ignition lockout. Replacing a faulty pressure switch with the correct OEM-spec part restores safe, reliable furnace operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HK06WC061 | Factory-calibrated W.C.
