OEM Carrier Two-Stage Gas Valve 24V 3.5" W.C. for Model PG96VAT30040ACAA

This OEM two-stage combination gas valve is the factory-authorized replacement for Carrier model PG96VAT30040ACAA 96% AFUE variable-speed gas furnaces. Originally supplied as part number EF33CW206 (superseded by EF33CW152), this valve controls gas flow to the burner assembly in two stages — low fire for mild demand and high fire for peak heating — allowing precise, efficient combustion. When the gas valve fails, symptoms include a furnace that attempts ignition but delivers no heat, a system that locks out after repeated ignition trials, or a complete loss of heating with the inducer and igniter cycling normally. Do not attempt to repair a faulty gas valve — replacement is required.

• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM valve built to exact Carrier specifications. OEM valves guarantee proper stage sequencing, pressure regulation, and safe shutoff.

Required tools: manifold gauge, leak-detection solution, 1/2" wrench, flathead screwdriver, multimeter. Always shut off gas supply and power before beginning. Verify inlet/outlet pressure with a manometer after installation.
