The genuine OEM Lennox 17A28 oil burner is responsible for igniting and controlling combustion inside your Lennox oil-fired furnace. It sprays a fine mist of fuel oil and mixes it with air to produce an even, efficient flame, delivering the steady heat output your Lennox system was built to provide. Every unit is manufactured to factory specifications for an exact fit in compatible models.
When this burner starts to fail, watch for hard or delayed ignition, a noisy or rumbling flame, puffback on shutdown, soot and carbon buildup, an oily odor, and climbing fuel costs. Frequent short cycling or uneven heating are further signs the burner is due for replacement.
An OEM Lennox 17A28 preserves the precise electrode gap, airflow, and nozzle positioning your equipment requires — specifications aftermarket parts often get wrong. That precision means restored efficiency, safer operation, and full compatibility with your Lennox furnace and its warranty. In stock now, ships same day before 3PM CST.
