Carrier LH32RF102 Burner Orifice

The Carrier LH32RF102 Burner Orifice is a precision-engineered OEM gas furnace part designed to regulate fuel flow within the burner assembly of high-efficiency Carrier, Bryant, and Payne units. As a critical HVAC burner spud, this component features a #38 drill size with a precise 0.101-inch diameter to ensure consistent manifold pressure and optimal BTU output for the combustion process. Replacing a clogged or corroded furnace burner orifice with this genuine Carrier replacement part is essential for maintaining the correct fuel-to-air ratio, preventing soot buildup, and avoiding uneven heating patterns across the heat exchanger.

Constructed from heavy-duty brass, the LH32RF102 is built to withstand high-temperature environments without deforming or losing calibration. It is a standard component for numerous packaged units and furnaces, including the 48VG and 48VT series. For contractors, utilizing genuine Carrier HVAC parts ensures exact fitment and helps maintain the design-specified efficiency of the equipment. Always verify your manifold pressure settings using a manometer after installation to ensure the Carrier LH32RF102 provides the exact gas flow required for the specific model's firing rate.

Key Benefits
