OEM Carrier Gas Valve 24V 3.5" W.C. Natural Gas 3/4" for Model PG8JVA060110AAJA

The Carrier EF33CW180 is the factory-specified OEM combination gas valve for the Carrier PG8JVA060110AAJA gas furnace. This valve controls the precise flow of natural gas to the burner assembly on every call for heat. When this valve fails — due to a faulty solenoid coil, stuck plunger, or internal diaphragm failure — the furnace will enter a lockout condition, displaying a no-heat fault with no flame established. Customers often report the inducer running normally but the burners never lighting, or the valve opening briefly and then snapping shut.

• Specs: 24V coil voltage | 3/4" NPT inlet connection | 3.5" W.C. outlet pressure (natural gas) | Hi-fire regulated @ 3.5" W.C. | Low-fire regulated @ 1.5" W.C. | Combination redundant safety valve design | Dimensions: 4.7 × 4.8 × 2.2 in.
• OEM vs Generic: This is a genuine Carrier OEM part — factory-matched to the exact solenoid draw, outlet pressure calibration, and flow rate of the PG8JVA060110AAJA burner assembly. Generic gas valves frequently have mismatched pressure setpoints that result in delayed ignition, nuisance lockouts, or improper combustion — all of which can void your equipment warranty.
• Install difficulty: 3/5 — Gas valve replacement requires shutting off the manual gas cock upstream, depressurizing the line, and confirming zero gas pressure before disconnecting. Tools needed: adjustable wrench, pipe thread sealant (yellow PTFE tape or gas-rated pipe dope), multimeter (verify 24VAC at valve terminals), manometer (confirm outlet pressure post-install). Leak-check all fittings with approved gas leak detector solution after reconnection. Recommended for licensed HVAC technicians.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships the same business day from our warehouse.
