Originally sold under part number \u003cstrong\u003eEF33CW206\u003c\/strong\u003e (also EF33CW206A) and manufactured by White-Rodgers (36J56-503), this valve has been superseded by the current OEM replacement \u003cstrong\u003eEF33CW152\u003c\/strong\u003e — a direct, drop-in substitute supplied by Carrier's Factory Authorized Parts division. The gas valve is the gatekeeper of combustion: it receives a 24V signal from the control board, opens in two stages (low fire → high fire), and meters gas flow at a precisely regulated pressure to the burner assembly. When it fails, your furnace will typically lock out after one or more ignition attempts, display a fault code, or simply produce no heat at all despite the inducer and igniter operating normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24 VAC coil voltage | 3.5\" W.C. outlet pressure | 1\/2\" NPT inlet \u0026amp; outlet | Two-stage operation (low\/high fire) | Natural gas standard; LP conversion kit compatible | Valve body length approx. 5\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a Factory Authorized Parts OEM valve engineered to Carrier's exact combustion tolerances. Off-brand valves frequently drift in outlet pressure calibration, causing rich or lean combustion, nuisance lockouts, and accelerated heat exchanger wear — especially critical in a 95% AFUE condensing furnace like the PG95XAT66120DAAA.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 4\/5\u003c\/strong\u003e — Gas valve replacement is an intermediate-to-advanced repair. Required tools: 1\/2\" \u0026amp; 3\/4\" open-end wrenches, leak-detection solution, manometer for outlet pressure verification, and a multimeter to confirm 24V at valve terminals. Always shut off the gas supply and de-energize the furnace before beginning. Post-installation leak check and pressure verification are mandatory.
