OEM Carrier Gas Valve 24V 1/2" Natural/LP for Model YAC48110YAC204AC

This OEM combination gas valve is the factory-specified replacement for the Carrier YAC48110YAC204AC packaged gas/electric unit. The gas valve is the critical component that receives a 24V signal from the control board and opens to allow metered gas flow to the burners. When it fails, the system will attempt ignition — the igniter will glow and the inducer will run — but no flame will establish, resulting in a lockout fault code. Other symptoms include intermittent heating, a gas valve that sticks open or closed, or abnormal gas pressure at the manifold.

• Specs: 24VAC coil voltage | 1/2" inlet × 1/2" outlet | Single-stage, slow-opening | Pressure set to 3.5" W.C. (Natural Gas) | Includes LP conversion kit | 0.28A draw | 50/60 Hz compatible
• OEM vs Generic: This is a genuine Carrier OEM valve engineered to exact factory tolerances for pressure regulation, coil response time, and safety shutoff. Aftermarket valves can drift on W.C. settings, causing rich or lean combustion and voiding equipment warranties.
• Install difficulty: 3/5 — Gas valve replacement requires shutting off the gas supply upstream and verifying zero pressure before disconnecting. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for manifold pressure verification, multimeter for 24V coil check. Gas leak test with approved solution is mandatory after installation. Recommended for licensed HVAC technicians.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for Carrier model YAC48110YAC204AC packaged gas/electric units. Verify your existing valve's inlet/outlet size, W.C. rating, and voltage from the unit data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — no guesswork required.
