OEM Carrier Gas Valve 24V 3.5" WC Natural Gas 1/2" for Model PG95ESAA66140DAA

This is the genuine OEM replacement gas valve (part number EF32CW151) for the Carrier PG95ESAA66140DAA 95% AFUE two-stage gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it opens and closes on demand from the control board, allowing precisely metered natural gas to flow to the burners for ignition. When this valve fails, the furnace will either lock out after several ignition attempts with no flame established, or refuse to ignite entirely, leaving you with a cold house and a flashing fault code on the control board.

• Specs: 24V coil voltage | 3.5" W.C. outlet pressure (factory set) | Natural gas | 1/2" inlet connection | White Rodgers 36J52-580 equivalent | Weight: 1.77 lb
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM valves are calibrated to exact outlet pressure tolerances from the factory, ensuring safe and efficient combustion. Generic valves may require manual pressure adjustment and can void your furnace warranty.
• Install difficulty: 3/5 — Gas work requires care. Shut off the manual gas supply before beginning. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter to verify 24V coil signal, and leak-detection solution. Always leak-test all connections after installation. A licensed HVAC technician is recommended if you are unfamiliar with gas line work.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
