OEM Carrier Gas Valve EF33CW201 for Model LC348TM401736

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.

  • Specs: OEM part number EF33CW201 | Combination gas valve | 24V coil voltage | Factory-matched inlet/outlet configuration for Carrier LC348TM401736
  • OEM vs Generic: This is a genuine OEM Carrier gas valve, ensuring exact coil voltage, port sizing, and pressure regulation matching the original factory specification. Generic valves may have inconsistent pressure ratings or coil tolerances, risking unreliable ignition and potential safety issues.
  • Install difficulty: 3/5 — Gas valve replacement requires shutting off the manual gas supply, relieving line pressure, and disconnecting wiring harnesses and gas fittings. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter, and screwdrivers. Always verify gas-tight connections with a leak detection solution after installation. Professional installation is recommended.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: This gas valve is the factory-specified replacement for Carrier model LC348TM401736.

Frequently Asked Questions

Does this Gas Valve fit my Carrier LC348TM401736?
Yes. This is the factory-specified OEM gas valve for the Carrier LC348TM401736. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the gas valve on my Carrier LC348TM401736?
Requires licensed HVAC technician. Gas valve work involves gas lines that must meet local building codes. Improper installation risks dangerous gas leaks. Buy the part yourself to save 40–60% on markup, then have your technician install it.
What symptoms mean I need a new gas valve?
Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this gas valve compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier gas valve?
Always use OEM. Gas valves must match exact pressure ratings, port configurations, and safety certifications. Non-OEM gas valves can create safety hazards and may violate building codes.
