OEM Carrier Two-Stage Gas Valve 24V 3.5" WC for Model PG95XAT36040BAAA

This OEM combination gas valve is the factory-specified replacement for the Carrier PG95XAT36040BAAA 95% AFUE two-stage gas furnace. It replaces original Carrier part number EF33CW206 (also EF33CW206A) and cross-references White-Rodgers part number 36J56-503, with the current OEM successor being EF33CW152. The gas valve is the heart of the combustion system — it receives a 24V control signal from the furnace control board and precisely meters natural gas flow into the heat exchanger at both low- and high-fire stages. When it fails, you'll typically see a no-heat condition, an ignition lockout fault code, or a furnace that starts briefly and shuts down before reaching setpoint temperature.

• Specs: Two-stage combination gas valve | 24 VAC control voltage | 3.5" W.C. outlet pressure | 1/2" inlet × 1/2" outlet | ~5" valve length | Natural gas (LP convertible) | 50/60 Hz
• OEM vs Generic: This is a genuine OEM-grade White-Rodgers valve manufactured to exact Carrier factory tolerances. Generic aftermarket valves frequently exhibit incorrect outlet pressure calibration, which can cause nuisance lockouts, incomplete combustion, or heat exchanger damage over time.
• Install difficulty: 4/5 — Gas valve replacement is a professional-level repair. Always shut off the manual gas supply valve and de-energize the furnace before beginning. Tools required: adjustable wrench, pipe thread sealant (gas-rated), manometer for pressure verification, and leak-detection solution. Confirm proper outlet pressure after installation. Licensed HVAC technician strongly recommended.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PG95XAT36040BAAA two-stage 95% AFUE gas furnace. Part number EF33CW206 has been superseded by EF33CW152 — both are fulfilled as the current OEM valve. Always verify your unit's data plate voltage (24V) and gas type before ordering. Our fitment team is available to confirm compatibility prior to purchase.
