OEM Carrier Two-Stage Gas Valve for Model PG95XAT48080BAAA (Replaces EF33CW206)

This OEM two-stage combination gas valve is the factory-authorized replacement for the Carrier PG95XAT48080BAAA 95% AFUE variable-capacity gas furnace. Originally supplied under part number EF33CW206 (also EF33CW206A) and manufactured by White-Rodgers (36J56-503), this valve controls the flow of natural gas into the burner assembly through both a first-stage (low-fire) and second-stage (high-fire) operation. When this valve fails, your furnace will typically enter a lockout condition — showing a fault code — with no ignition attempt completing, no heat output, or a hard shutoff immediately after burner light-off.

• Specs: 24 VAC low-voltage control | Two-stage (low/high fire) operation | 3.5" W.C. outlet pressure | 1/2" NPT inlet & 1/2" NPT outlet | Valve body length approx. 5" | Factory-set for natural gas (LP conversion kit available separately)
• OEM vs Generic: This is a genuine OEM Factory Authorized Part engineered to Carrier's exact pressure and flow specifications. Aftermarket gas valves may not hold calibrated outlet pressure ratings, risking improper combustion, carbon monoxide risk, or voided equipment warranty.
• Install difficulty: 4/5 — Gas valve replacement is an intermediate-to-advanced repair. Shut off gas supply at the manual shutoff before beginning. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and a combustible gas leak detector. Licensed HVAC technician strongly recommended.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our stocked warehouse. Free standard shipping on this order.
