Carrier 326643-704 Burner Assembly
When you are dealing with a furnace that refuses to ignite or suffers from inconsistent burner tracking, a precision-engineered Carrier 326643-704 Burner Assembly is the specified solution for restoring reliable combustion. This genuine OEM furnace burner replacement is designed as a 5-inshot configuration, ensuring the venturi effect is optimized for a stable, blue flame across the heat exchanger. As a veteran-grade Carrier HVAC replacement part, it addresses common failure points like port clogging, corrosion, or warped burner faces that lead to delayed ignition or resonance issues during the heating cycle. Using the 326643-704 burner assy ensures that the gas-to-air mixture remains within the manufacturer’s stoichiometric parameters, maintaining peak furnace heating efficiency and preventing unnecessary stress on the flame sensor or igniter. This assembly is a direct-fit for multiple Carrier, Bryant, and Payne residential furnaces, making it a staple for contractors looking to eliminate callbacks related to poor combustion performance.
Key Benefits:- Precise 5-Inshot Design: Engineered to provide uniform gas distribution and consistent flame carry-over for reliable ignition.
- OEM Compatibility: Guaranteed to align with original factory specifications for many Carrier and Bryant furnace models, ensuring exact manifold positioning.
- Durable Construction: Built with high-grade materials to withstand thermal cycling and minimize the risk of flash-back or soot accumulation.
- Optimized Combustion: Designed to maintain the correct primary air ratio, reducing carbon monoxide risk and maximizing thermal output.
- How do I know if my burner assembly needs replacement rather than just cleaning? If you observe physical warping, significant rust scaling that obstructs the ports, or if the burner faces are "waist-ing" out, a full replacement is necessary to ensure safety and proper drafting.
- Will this assembly fix a 'flame rollout' error code? While a rollout can be caused by a cracked heat exchanger or flue blockage, a dirty or compromised burner assembly often causes the improper flame tracking that trips the rollout switch.
- Is the gas orifice included with the Carrier 326643-704? Typically, this is the burner assembly itself; you should retain your existing orifices or verify the BTU rating if replacing them to match the manifold pressure and gas type (Natural Gas vs. Propane).
