Carrier 326643-703 Burner
The Carrier 326643-703 Burner is a critical 4-inch inshot burner assembly designed for high-efficiency gas furnaces. As a veteran-grade OEM furnace replacement part, this component ensures precise fuel-to-air ratios, facilitating a stable and consistent flame pattern essential for optimal heat exchange. Engineered for Carrier, Bryant, and Payne residential and commercial heating units, this assembly features a compact profile, measuring approximately 3.3 inches in length and 5.6 inches in width. Integrating a genuine HVAC burner assembly like the 326643-703 is vital for maintaining the combustion integrity of the system and preventing common ignition failures. The in-shot burner design facilitates a powerful, directional flame that fires directly into the heat exchanger, maximizing thermal transfer while minimizing carbon buildup. For contractors performing seasonal maintenance or emergency repairs, this factory-spec component serves as a direct drop-in replacement to restore original equipment performance standards across compatible gas furnace burner platforms.
Key Benefits- Precise Combustion Control: Designed to maintain the correct venturi effect for a reliable blue flame and efficient fuel consumption.
- OEM Compatibility: Specifically engineered as a direct replacement for Carrier 326643-703, Bryant, and Payne furnace models.
- Durable Construction: Built from heavy-duty materials to withstand high-temperature environments and resist premature oxidation.
- Inshot Design: Optimizes heat distribution within the combustion chamber for improved system efficiency.
Which furnace brands are compatible with the 326643-703 burner?
This inshot burner assembly is the factory-authorized replacement for many Carrier, Bryant, and Payne gas furnaces. Always verify your specific model number before installation.
What are the symptoms of a failing inshot burner?
Common signs include uneven flame distribution, "rumbling" noises during combustion, soot accumulation, or delayed ignition due to clogged or corroded burner ports.
Is the 326643-703 a direct-fit replacement part?
Yes, as a genuine OEM part, it is designed to fit the existing manifold and mounting brackets without the need for field modifications, ensuring a faster turnaround for service technicians.
