OEM Carrier Gas Valve EF32CB212 for Model GA1AAD042070AAJA

This is the factory OEM combination gas valve (part number EF32CB212) for the Carrier GA1AAD042070AAJA gas furnace. The combination gas valve controls the flow of gas to the burners by responding to 24V signals from the integrated furnace control board. When this valve fails, the furnace will typically attempt ignition, the hot surface igniter will glow, but no gas will flow — resulting in a lockout condition and a no-heat call. In some cases a failed valve may also cause a continuous gas smell or erratic burner behavior. Replacing with an OEM-matched valve ensures correct inlet/outlet sizing, pressure regulation, and coil voltage compatibility.
