OEM Carrier Two-Stage Gas Valve 24V 3.5" w.c. for Model PG96VAT30040ABAA

This OEM two-stage gas valve is the factory-specified replacement for Carrier model PG96VAT30040ABAA 96% AFUE gas furnaces. Originally supplied as Carrier part EF33CW206 (also EF33CW206A) and manufactured by White-Rodgers as 36J56-503, this valve has been superseded by the current OEM replacement part EF33CW152 — a direct drop-in with identical specifications. The gas valve is a low-voltage controlled combination valve that meters gas flow into the combustion chamber and regulates manifold pressure for safe, efficient ignition. When it fails, the furnace will attempt ignition but produce no flame — often resulting in a lockout code — or will deliver insufficient heat output on one or both stages.

• Specs: 24 VAC control voltage | 3.5" w.c. outlet pressure | 1/2" NPT inlet × 1/2" NPT outlet | ~5" valve body length | Two-stage operation (low/high fire) | Natural gas standard; convertible to propane
• OEM vs Generic: OEM valves meet Carrier's exact factory pressure tolerances and agency listings. Generic or off-brand valves can deliver inconsistent manifold pressure, causing short-cycling, sooting, or unsafe combustion conditions — a critical concern on high-efficiency furnaces like the PG96VAT30040ABAA.
• Install difficulty: 4/5 — Gas valve replacement involves working on live gas lines. Licensed HVAC technician required. Tools needed: pipe wrench, gas leak detection solution, manometer for pressure verification, 1/4" hex driver. Always shut off gas supply and verify with a manometer after installation.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for Carrier model PG96VAT30040ABAA 96% AFUE two-stage furnaces. OEM part EF33CW206 / EF33CW206A has been superseded by EF33CW152; this listing supplies the current authorized replacement. Verify your data plate voltage and inlet/outlet sizing before ordering.
