The gas valve controls the flow of gas to the burners during each heating cycle — opening on command from the control board after the pressure switch and igniter confirm safe operating conditions. When the gas valve fails, the result is typically a complete loss of heat: the inducer runs, the igniter glows, but no flame is established, triggering a lockout condition. In some cases, a faulty valve causes intermittent heating or a furnace that shuts down mid-cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number EF33CW201 | Combination gas valve | 24V coil voltage | Factory-calibrated inlet\/outlet pressure settings | Direct drop-in replacement for Carrier LC348LC400400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier gas valve manufactured to exact factory pressure tolerances and safety certifications.
