The gas valve is a critical safety and control component — it regulates the flow of natural gas or propane into the burner assembly in direct response to commands from the integrated furnace control board. When this valve fails, the result is a complete loss of heat: the igniter may glow, the inducer may run, but no flame is established because gas never reaches the burners. Common failure symptoms include a \u003cstrong\u003eno-heat lockout\u003c\/strong\u003e, error codes indicating failed ignition, or a gas valve that opens but delivers insufficient flow.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e \u003cstrong\u003e36C21-411\u003c\/strong\u003e (White-Rodgers \/ Emerson) | Cross-reference: \u003cstrong\u003eEF26CK201\u003c\/strong\u003e — both are factory-authorized replacements for Carrier model YAC36100YAC304.
