OEM Carrier Gas Valve 24V 3/4" Single Function for Model YAC36100YAC105

This is the factory-specified OEM combination gas valve for the Carrier YAC36100YAC105 furnace, cross-referencing OEM part numbers 36C21-411 (White-Rodgers / Emerson) and EF26CK201 (Carrier). The gas valve is the electromechanical gatekeeper of your heating system — it receives a 24 VAC signal from the control board and opens to allow natural gas or propane into the combustion chamber. When it fails, the furnace will attempt ignition but produce no flame, resulting in a lockout fault, no-heat condition, or a continuous blinking error code on the control board. Do not attempt to repair a faulty gas valve; always replace with an exact OEM-matched unit.

• Specs: 24 VAC coil voltage | 3/4" inlet × 3/4" outlet | Single-function, snap-open operation | 0.23A coil draw | 1/2 PSI max inlet pressure | Supports Natural Gas and Propane (LP) | Side tap ports included
• OEM vs Generic: This OEM valve is factory-calibrated to precise gas pressure tolerances for the YAC36100YAC105. Generic valves risk improper gas regulation, flame instability, and voided equipment warranties. Always specify OEM on a gas-carrying component.
• Install difficulty: 3/5 — Shut off gas supply at the manual shutoff and lock out electrical power before beginning. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and a leak-detection solution. Post-installation gas leak check is mandatory. Recommend licensed HVAC technician for gas valve replacement.
