OEM Carrier Gas Valve 24V 3.5" WC Natural Gas for Model PG8JAA042090AGJA

This OEM combination gas valve (part# EF32CW210) is the factory-specified replacement for the Carrier PG8JAA042090AGJA gas furnace. The gas valve is the critical component that controls natural gas flow to the burner assembly — receiving a 24V signal from the control board to open, meter, and regulate gas pressure at the factory-set 3.5" W.C. outlet. When the gas valve fails, the furnace will typically attempt ignition, fail to light, and enter a hard lockout — leaving your home with no heat. In some cases a failed valve will prevent the inducer from proving pressure or cause repeated ignition retries with no flame establishment.

• Specs: 24V coil voltage | 50/60 Hz | Natural gas | 3.5" W.C. outlet pressure (factory set) | 1/2" NPT inlet/outlet | Replaces cross-reference 36J24-618 (White Rodgers)
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, built to exact pressure-regulation tolerances. Aftermarket gas valves may ship with incorrect outlet pressure settings, causing dangerous over-gassing or nuisance lockouts that void furnace warranties.
• Install difficulty: 4/5 — Gas valve replacement involves working on a live gas line. Always shut off the gas supply at the service valve, verify zero pressure with a manometer before disconnecting fittings, and re-test for leaks with approved leak-detection solution after installation. Tools needed: adjustable wrench, pipe thread sealant (yellow PTFE), multimeter, manometer. Licensed HVAC technician strongly recommended.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
