OEM Carrier Gas Valve 36C21-411 / EF26CK201 for Model YAC36100YAC305A

This OEM combination gas valve is the factory-specified replacement for the Carrier YAC36100YAC305A packaged unit. The gas valve regulates the flow of natural gas or propane to the burner assembly, opening on a call for heat and closing immediately when the thermostat is satisfied or a safety lockout is triggered. When the gas valve fails, symptoms include no heat output, a failed ignition sequence with the inducer running normally, or a fault code indicating gas flow is not being proven by the flame sensor.
