The Goodman 10735102S is a genuine OEM Beckett burner assembly for the WGGE4330A045MAB gas furnace. The burner mixes fuel and air and holds a stable flame across the heat exchanger for efficient, clean combustion. A warped, rusted, or clogged burner can cause rough ignition, uneven or yellow flames, sooting, delayed light-off, and nuisance safety lockouts.
The OEM Beckett burner delivers the exact port sizing and flame characteristics the WGGE4330A045MAB was certified with, ensuring proper flame carryover and a stable signal at the flame sensor. Generic burners can alter the air-fuel mix, leading to inconsistent ignition or sooting. The factory part keeps combustion tuned to spec.
Moderate (3 of 5). Shut off power and gas, remove the burner assembly, transfer or align the igniter and sensor as needed, and reinstall with correct clearances. Plan on 30–45 minutes. Because it involves the gas train, professional installation is recommended if you're unsure.
