OEM Carrier Combination Gas Valve 24V 3.5" WC Natural Gas for Model PG95ESAA36040BAA

This is the factory OEM replacement combination gas valve (part #EF32CW151) for the Carrier PG95ESAA36040BAA 95% AFUE two-stage gas furnace. The gas valve is the critical component that controls the flow of natural gas to the burner assembly on each heating call. When it fails, your furnace will typically enter a lockout condition — you may see a no-heat fault code, hear clicking with no ignition, or notice the inducer and igniter cycling without any flame being established. In some cases a stuck-open valve can cause delayed ignition with a loud boom on startup, which is a safety hazard requiring immediate replacement.

• Specs: 24V coil voltage | 3.5" W.C. (water column) outlet pressure — factory set | Natural gas (NAT) | 1/2" NPT inlet connection | White Rodgers cross-reference: 36J52-580 | Weight: 1.77 lb
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact pressure tolerances for the PG95ESAA36040BAA. Aftermarket valves frequently deviate from the factory 3.5" W.C. set point, causing incomplete combustion, nuisance lockouts, and potential carbon monoxide risk — always use OEM on combination gas valves.
• Install difficulty: 3/5 — Gas work requires caution. Shut off the manual gas shutoff upstream before starting. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), 1/4" nut driver for wire harness, manometer to verify outlet pressure after install. We strongly recommend licensed HVAC technician installation for gas valve replacements.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day when ordered by 3 PM local time. Orders over $99 qualify for free ground shipping.
