OEM Carrier Two-Stage Combination Gas Valve EF33CW206 for Model PG96VAT42060BBAA

This is the factory-specified OEM two-stage combination gas valve for the Carrier PG96VAT42060BBAA 96% AFUE variable-speed gas furnace. Manufactured by White Rodgers (model 36J56-503) to exact Carrier specifications, this valve serves as the gatekeeper between your gas supply and the burner assembly. It opens on first-stage call for heat at a reduced gas flow rate, then opens fully on second-stage demand — delivering precise, efficient combustion across all firing rates. When this valve fails, the furnace will lock out with no gas flow, leaving you with no heat. Common symptoms include the inducer running normally but the burners never lighting, or an error code indicating gas valve fault after igniter glow is confirmed.

• Specs: Two-stage combination gas valve | 24 VAC coil voltage | 1/2" NPT inlet × 1/2" NPT outlet | Approximately 5" valve length | Natural gas (factory set) | Convertible to LP/propane | 3.5" W.C. outlet pressure
• OEM vs Generic: This OEM valve is engineered to Carrier factory tolerances, ensuring proper stage-one and stage-two pressure regulation, leak-proof seat integrity, and accurate solenoid response times. Off-brand replacements risk improper gas pressure delivery, which can cause nuisance lockouts, incomplete combustion, or unsafe operation.
• Install difficulty: 4/5 — Gas valve replacement involves working directly with live gas lines and high-voltage furnace wiring. Shut off gas supply at the manual shutoff before beginning. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), 1/4" nut driver, manometer for outlet pressure verification, leak-detection solution. Licensed HVAC technician strongly recommended.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse. OEM part number EF33CW206 (also fits EF33CW206A); superseded by EF33CW152 where noted.
