Carrier EF33CW180 Gas Valve

The Carrier EF33CW180 Gas Valve is an essential OEM component designed for high-precision fuel regulation in residential and light commercial furnaces. Operating on a standard 24V gas valve electrical system, this unit is factory-set for natural gas with a 3.5" W.C. high-fire manifold pressure. As a veteran-grade furnace gas valve replacement, it features a 3/4" NPT inlet and outlet, ensuring maximum flow capacity for larger BTU applications. Built by White-Rodgers (Model 36J55-618) for the Carrier family of brands, including Bryant and Payne, this 2stage gas valve provides the slow-opening characteristic required for smooth ignition and quiet operation.

For technicians performing a Carrier furnace repair, the EF33CW180 offers a direct-fit solution for models like the 58CTA and 312AAV series. This valve is engineered to handle a maximum inlet pressure of 14" W.C. and integrates seamlessly with direct spark or hot surface ignition systems. By utilizing this genuine Carrier HVAC part, contractors ensure the system maintains its original design specifications and pressure modulation, preventing issues like short-cycling or delayed ignition often found with universal alternatives.

• Precise Pressure Regulation: High-fire regulated at 3.5" W.C. and low-fire at 1.5" W.C. for consistent thermal output.
• Slow-Opening redundant valve: Enhances safety and quiet ignition by gradually introducing fuel to the burner assembly.
• High-Flow 3/4" Connection: Matches original equipment specs for high-capacity heating units without restrictive flow.
• OEM Compatibility: Replaces older ICP and Carrier numbers including EF33CW192 and 36J55-618.

• Can this valve be converted to Liquid Propane (LP)? Yes, though it is factory-configured for natural gas, it is compatible with a manufacturer-approved LP conversion kit.
• What are the symptoms of a failing EF33CW180 valve? Common indicators include the furnace failing to ignite, "no heat" calls, or the gas valve clicking without allowing flow.
• Does this include the barbed pressure tap? Yes, this model includes the standard pressure taps for verifying and adjusting manifold pressure during installation.
