OEM Carrier Two-Stage Gas Valve EF33CW180 for Model PG8JVA066135AAJA
This is the genuine OEM replacement gas valve for the Carrier PG8JVA066135AAJA two-stage gas furnace. The combination gas valve is the heart of your heating system — it regulates gas pressure and flow to the burners in response to commands from the control board. When this valve fails, the furnace will either produce no heat at all, lock out after repeated ignition attempts, or fail to modulate properly between low- and high-fire stages. Replacing it with the exact factory-specified OEM part ensures your furnace operates safely and at rated efficiency.
- Specs: OEM Part # EF33CW180 | 24V coil voltage | Two-stage operation | Hi-Fire: 3.5" W.C. | Low-Fire: 1.5" W.C. | 3/4" NPT inlet/outlet | Natural gas configuration
- OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket substitute. OEM gas valves are factory-calibrated to exact pressure specifications, ensuring safe combustion and proper two-stage modulation. Aftermarket valves may deviate on pressure regulation, risking unsafe gas delivery, nuisance lockouts, or voided equipment warranty.
- Install Difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, relieving line pressure, and transferring wiring harnesses and gas line connections. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), flathead screwdriver, multimeter. Important: This work should be performed by a licensed HVAC technician. After installation, always perform a leak test with approved leak-detection solution before restoring power.
- Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
Compatibility: Engineered for the Carrier PG8JVA066135AAJA two-stage natural gas furnace.
