Goodman B4089343 #43 Burner Orifice

The Goodman B4089343 is a precision-drilled brass burner orifice (size #43) engineered for the ADS80703ANA gas furnace and compatible Goodman/Amana models. The orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and proper input rating. A clogged, corroded, or incorrectly sized orifice causes poor combustion, yellow flames, sooting, or lockouts — making this a critical maintenance and repair component.

Specifications

Orifice size: #43
Material: machined brass
Application: gas furnace main burner
Fits: Goodman ADS80703ANA and compatible models
OEM Part Number: B4089343

OEM vs. Generic

The OEM B4089343 guarantees the exact drill size and thread pitch for correct gas input and safe combustion. Generic equivalents may vary slightly in bore diameter, which can alter the firing rate. For combustion-critical components like orifices, OEM is strongly recommended to maintain manufacturer input specs and warranty compliance.

Install Difficulty

Easy (1/5). Shut off gas and power, unthread the old orifice from the manifold with a wrench, thread in the replacement, and leak-check with soapy water. Should take under 15 minutes per orifice for a qualified technician.
