This is the factory OEM combination gas valve (part number EF33CW201) designed as a direct replacement for the Carrier LC348TM401736 furnace. The gas valve is the critical component that regulates and controls the flow of gas to the burners during each heating cycle. It receives a 24V signal from the control board and opens to allow gas flow upon a successful ignition sequence. When this valve fails, the most common symptoms include no heat output, burners that fail to light despite a functioning igniter and flame sensor, or a furnace that locks out after repeated failed ignition attempts. In some cases, a faulty gas valve may also cause delayed ignition or intermittent heating.
Compatibility: This gas valve is the factory-specified replacement for Carrier model LC348TM401736. Verify your existing valve's part number and inlet/outlet orientation against your unit's data plate and wiring diagram before ordering. If you have any fitment questions, our HVAC parts specialists are available to confirm compatibility before you purchase. Order today for same-day shipping.
