OEM Carrier Two-Stage Gas Valve 24V 3.5" W.C. Natural Gas for Model PG8MVA048090AAJA

This is the genuine OEM two-stage combination gas valve for the Carrier PG8MVA048090AAJA gas furnace. The gas valve is the critical control component that meters and regulates natural gas flow to the burners on both low-fire and high-fire stages. When this valve fails, the furnace will typically ignite briefly and then shut down, present a no-heat lockout fault code, or fail to open entirely — leaving your home without heat. Replacing it with the correct factory-spec OEM part (EF33CW180) ensures safe, calibrated gas pressure delivery and restores two-stage efficiency to your system.

• Specs: 24V coil voltage | 3/4" inlet & outlet | Hi-fire regulated @ 3.5" W.C. | Low-fire regulated @ 1.5" W.C. | Natural gas | Two-stage (modulating) operation | OEM Part# EF33CW180
• OEM vs Generic: This is a genuine Carrier factory-authorized part. Generic or aftermarket gas valves may not deliver the precise hi-fire/low-fire pressure differentials required by two-stage furnace operation, risking incomplete combustion, nuisance lockouts, or voided manufacturer warranty.
• Install difficulty: 3/5 — Gas valve replacement requires shutting off the gas supply and verifying zero pressure before disconnecting fittings. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and a multi-meter to confirm 24V signal at valve terminals. Always perform a leak test after reinstallation. Professional installation strongly recommended if unfamiliar with gas work.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
