OEM Carrier 2-Stage Gas Valve EF33CW206 for Model PG95XAT60100CAAA

This OEM 2-stage combination gas valve is the factory-specified replacement for the Carrier PG95XAT60100CAAA high-efficiency gas furnace. Manufactured by White-Rodgers (part # 36J56-503), the gas valve is the heart of your furnace's combustion system — it meters and regulates the flow of natural gas into the burner assembly at both low-fire and high-fire stages. When this valve fails, the furnace will typically light briefly and then shut down into a safety lockout, fail to produce any heat at all, or throw a fault code indicating a gas valve or pressure fault. Replacing it with the correct OEM part restores factory-calibrated gas pressure and ensures safe, reliable two-stage operation.

• Specs: Two-stage combination gas valve | 24 VAC coil voltage | 3.5" W.C. outlet pressure | 1/2" NPT inlet × 1/2" NPT outlet | Valve body length ~5" | Natural gas (field-convertible to LP/propane) | White-Rodgers cross-reference: 36J56-503 | Also covers EF33CW206A variant
• OEM vs Generic: This is the exact factory-matched OEM White-Rodgers valve specified by Carrier for the PG95XAT60100CAAA. OEM gas valves maintain precise regulated outlet pressure (3.5" W.C.) within tight tolerances. Aftermarket valves may ship with incorrect pressure calibration, risking incomplete combustion, sooting, or nuisance lockouts — a critical safety concern on a 95% AFUE furnace.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician or gas fitter. Requires: gas leak detection solution, 1/2" pipe wrench, 7/16" nut driver, multimeter, and wire labels. Always turn off gas supply and disconnect power before beginning. Verify outlet pressure with a manometer after installation. Do not attempt DIY on any gas-carrying component.
• Warranty: 1-year OEM factory warranty on new parts. Ships same business day from our warehouse when ordered before 3 PM local time.
