OEM Carrier Replacement Gas Valve EF33CW204 for Model PG9UAA060100AASA

This is the OEM factory-specified combination gas valve for the Carrier PG9UAA060100AASA packaged gas/electric unit. The gas valve is the critical component that regulates natural gas or propane flow from the supply line to the burner assembly. It operates under direct command of the integrated furnace control (IFC) board — opening on a confirmed call for heat and closing immediately upon flame loss or system lockout. A failed gas valve typically presents as a no-heat condition where the inducer and igniter both sequence correctly, yet no flame is ever established, or as a hard lockout fault code on the control board.

• Specs: OEM Part Number EF33CW204 | Combination gas valve | Factory-matched inlet/outlet sizing | 24V coil actuation | Compatible with natural gas and LP (verify configuration)
• OEM vs Generic: This is a genuine OEM Carrier valve manufactured to exact factory pressure and flow specifications. Aftermarket valves may differ in seat tolerances, coil sensitivity, or outlet pressure calibration — compromising combustion efficiency and safety certification compliance.

Tools needed: adjustable wrench, pipe thread sealant (gas-rated), 1/4" nut driver, manometer for outlet pressure verification. Always perform a leak test with approved solution after reinstallation. Recommend licensed HVAC technician for this repair.
