OEM Carrier Two-Stage Gas Valve 24V 3.5" W.C. for Model PG95XAT30040AAAA

This OEM two-stage gas valve is the factory-specified replacement for the Carrier PG95XAT30040AAAA 95% AFUE gas furnace. Originally supplied as part number EF33CW206 (White-Rodgers 36J56-503), this valve is now superseded by the current OEM replacement EF33CW152 — a direct drop-in with identical fit, form, and function. The gas valve is the heart of your furnace's combustion system: it opens on a 24VAC signal from the control board to allow precisely regulated gas flow into the burner assembly. When it fails, the furnace will attempt ignition and then lock out, or produce no heat at all. Common symptoms include a no-heat condition, short cycling after ignition attempt, or a fault code indicating gas valve failure on the control board.

• Specs: 24 VAC low-voltage control | 3.5" W.C. outlet pressure (natural gas) | 1/2" inlet × 1/2" outlet | Two-stage operation | Valve length approximately 5" | Convertible to LP/propane with conversion kit
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (White-Rodgers manufactured), meeting exact factory design-life testing and agency safety listings. Generic aftermarket valves may not meet the precise pressure regulation tolerances required by a 95% AFUE modulating furnace, risking combustion inefficiency, nuisance lockouts, or unsafe operation.
• Install difficulty: 4/5 — Gas valve replacement involves working on live gas lines and should be performed by a licensed HVAC technician. Tools required: adjustable wrench, pipe thread sealant, manometer for outlet pressure verification, and a combustible gas leak detector. Always shut off gas supply and verify zero pressure before disconnecting. Relight and test for leaks after installation.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse.
