OEM Carrier Combination Gas Valve EF33CW204 for Model PG9UAA060080AASA

This is the factory-specified OEM combination gas valve for the Carrier PG9UAA060080AASA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of gas from the supply line to the burners in response to signals from the control board. When this valve fails, the furnace will complete its ignition sequence but produce no heat, often resulting in a lockout fault code indicating no gas flow or flame failure. Common symptoms include a furnace that ignites momentarily then shuts down, or one that never fires at all.

• Specs: OEM Part Number EF33CW204 | Combination gas valve | Factory-calibrated inlet/outlet pressure | 24V coil actuation | Compatible with natural gas and LP configurations (verify gas type on data plate)
• OEM vs Generic: This is a genuine OEM Carrier gas valve built to exact factory tolerances for pressure regulation, coil response, and safety shutoff. Aftermarket valves can suffer from imprecise pressure settings, delayed shutoff response, and reduced service life — risks not worth taking on a gas-carrying component.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician. Required tools include pipe wrenches, gas leak detection solution, manometer for inlet/outlet pressure verification, and a multimeter to confirm 24V coil voltage. Always shut off the manual gas supply and power before beginning. Leak-test all fittings after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
