OEM Carrier Combination Gas Valve EF33CB192 for Model PG9MTAV36075ABSS

This is the factory OEM combination gas valve (part number EF33CB192) specified for the Carrier PG9MTAV36075ABSS gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates gas pressure, controls main burner flow, and responds to 24V signals from the integrated furnace control (IFC) board. When this valve fails, the furnace will attempt ignition but deliver no heat, typically triggering a pressure or gas-flow fault lockout code. Common symptoms include: no flame despite a glowing igniter, error codes indicating valve failure, or a furnace that runs the inducer but never lights the burners.

• Specs: OEM Carrier combination gas valve | Part No. EF33CB192 | 24V coil voltage | Factory-calibrated outlet pressure | Direct drop-in replacement — no modifications required
• OEM vs Generic: This is a genuine OEM part built to exact Carrier factory specifications. Generic or aftermarket gas valves may have incorrect pressure settings or coil ratings, risking unsafe operation, failed inspections, or voided furnace warranties.
• Install Difficulty: 4/5 — Gas valve replacement involves working with live gas lines and must comply with local codes. Shut off gas supply at the manual shutoff valve before beginning. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and a combustible gas leak detector. We strongly recommend a licensed HVAC technician perform this installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
