OEM Carrier Two-Stage Gas Valve EF33CW206 (White Rodgers 36J56-503) for PG95XAT30040ABAA

This OEM two-stage combination gas valve is the factory-specified replacement for the Carrier PG95XAT30040ABAA 95% AFUE gas furnace. Manufactured by White Rodgers (model 36J56-503) to exact Carrier specifications, this valve controls the flow of natural gas into the combustion chamber on both low-fire and high-fire stages. When the gas valve fails, the furnace will attempt ignition, the hot surface igniter will glow, but no gas will flow — resulting in a failed ignition lockout, error codes, or a complete no-heat condition. A failed valve may also cause intermittent heating, failure to reach second-stage firing, or a gas odor if the valve seat is compromised.

• Specs: Two-stage combination gas valve | 24 VAC low-voltage control coil | 1/2" inlet × 1/2" outlet | Valve length ~5" | Natural gas (LP conversion kit available) | Replaces White Rodgers 36J56-503 | Also fits EF33CW206A variant
• OEM vs Generic: This is a factory-authorized OEM valve built to Carrier's exact pressure and flow tolerances. Generic aftermarket valves may not maintain the precise 3.5" W.C. manifold pressure required for safe, efficient combustion on the PG95XAT30040ABAA — risking nuisance lockouts, sooting, or carbon monoxide risk.
• Install Difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, depressurizing the line, and disconnecting wiring harness and gas fittings. Tools required: adjustable wrench, pipe thread sealant (gas-rated), manometer for manifold pressure verification, and multimeter. A licensed HVAC technician or gas fitter is strongly recommended. A gas leak test must be performed after installation.
• Warranty: OEM 1-year factory warranty. Ships same business day from our warehouse in original manufacturer packaging.
