OEM Carrier Two-Stage Gas Valve 24V for Model PG95XAT66120DBAA (EF33CW206 / EF33CW152)

This OEM two-stage combination gas valve is the factory-specified replacement for the Carrier PG95XAT66120DBAA 95% AFUE gas furnace. The gas valve is the critical fuel-control component that meters and delivers natural gas from the supply line into the heat exchanger's burner assembly. When it fails, the furnace will attempt ignition but no gas will flow — resulting in a no-heat condition, repeated ignition lockouts, or a fault code indicating a gas valve failure. A faulty valve that sticks open is also a serious safety hazard requiring immediate replacement.

• Specs: Two-stage combination gas valve | 24 VAC control voltage | 1/2" NPT inlet × 1/2" NPT outlet | Valve body length ~5" | Natural gas configured (convertible to LP) | Replaces OEM part number EF33CW206 / EF33CW206A and White-Rodgers 36J56-503; current OEM successor: EF33CW152
• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM-equivalent valve built to exact Carrier design-life specifications. Generic aftermarket valves may not meet the precise inlet pressure and flow-rate tolerances required by the PG95XAT66120DBAA, risking nuisance lockouts, improper combustion, and voided equipment warranties.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician. Shut off the gas supply and disconnect 24V control wiring before removal. Tools required: adjustable wrench, pipe thread sealant, 1/4" and 5/16" nut drivers, manometer for outlet pressure verification (3.5" w.c. natural gas), and combustion analyzer. Always leak-test all connections with approved leak detection solution after installation.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our climate-controlled warehouse. Expedited overnight options available at checkout.
