Natural Gas for Model PG8MVA048090AAJA\u003c\/h1\u003e\u003cp\u003eThis is the genuine OEM two-stage combination gas valve for the \u003cstrong\u003eCarrier PG8MVA048090AAJA\u003c\/strong\u003e gas furnace. The gas valve is the critical control component that meters and regulates natural gas flow to the burners on both low-fire and high-fire stages. When this valve fails, the furnace will typically ignite briefly and then shut down, present a no-heat lockout fault code, or fail to open entirely — leaving your home without heat. Replacing it with the correct factory-spec OEM part (EF33CW180) ensures safe, calibrated gas pressure delivery and restores two-stage efficiency to your system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V coil voltage | 3\/4\" inlet \u0026amp; outlet | Hi-fire regulated @ 3.5\" W.C. | Low-fire regulated @ 1.5\" W.C. | Natural gas | Two-stage (modulating) operation | OEM Part# EF33CW180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized part.

Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and a multi-meter to confirm 24V signal at valve terminals.
