Nordyne 904823 Burner Assembly

The Nordyne 904823 Burner Assembly is a direct-replacement gas furnace burner engineered for mobile home furnace repair and residential HVAC applications. This four-tube burner utilizes a 1/2" NPT steel manifold connection to deliver a consistent, high-efficiency flame pattern, ensuring the reliable heat transfer required for condensing and non-condensing systems. As a veteran-grade OEM furnace part, the 904823 is designed to withstand thermal stress and resist the warping or clogging common in older burner boxes. It is compatible with a wide range of Intertherm, Miller, and Nordyne units, providing a precise fit for the primary heat exchanger cells. For service contractors, this assembly enables a streamlined furnace burner replacement, restoring proper combustion alignment and fuel-to-air ratios without time-consuming field modifications. By maintaining optimal burner integrity, you reduce the risk of nuisance trips on flame rollout limit switches and improve overall system AFUE.

• Precision Flame Alignment: The four-tube burner design ensures uniform heat distribution across the heat exchanger, preventing localized hot spots.
• Heavy-Duty Steel Construction: Built to handle high-temperature ignition cycles, reducing the likelihood of scale buildup or structural oxidation.
• Simplified Installation: Standardized mounting holes and a 1/2" NPT orifice inlet allow for a straightforward swap in packaged units or split systems.
• Reliable Ignition: Engineered for seamless compatibility with hot surface igniters (HSI) to ensure rapid and quiet cross-lighting.

What are the signs that a burner assembly needs replacement?
Technicians should look for heavy scale buildup, rusted ports, or any signs of warping (flame crowning). If you observe a "lazy" yellow flame or if the flame sensor isn't receiving a consistent signal, the burner ports may be obstructed, requiring a fresh 904823 assembly.

Is the Nordyne 904823 compatible with propane (LP) conversions?
Yes, but you must transfer the mixer (spoiler) screws and use the appropriate LP orifices from the original setup or a conversion kit. Failure to adjust for the higher pressure of propane can cause hazardous soot accumulation.

Does this assembly include the igniter or flame sensor?
This part is the primary burner assembly frame and tubes. While it features the necessary brackets for mounting components, the hot surface igniter and flame sensor must be ordered separately or transferred from the existing unit if they are still within spec.
