The burner in your furnace is where air and gas meet and combust. It is a critical part of your furnace, and problems with it can result in heat loss.

What Is the Burner?
The burner is the part of your furnace through which the natural gas flows and ignites into jets that heat the air for your home. The burner is a rectangular-shaped component with 4-8 short metal tubes that are fed the gas from the furnace’s manifold. An igniter at the right side of the burner ignites the gas jets, and a flame sensor at the other end monitors the flames. The burner heats the heat exchanger, which provides the warm air for your home.
Common Problems with Burners
Here are some common problems that can develop with a burner:
- Rust/corrosion – any kind of rust or corrosion on your burner means that the burner needs to be replaced. A rusty burner can leak gas and/or malfunction, leading to problems with heating.
- Problems with the igniter – there are two types of igniters: intermittent pilot and hot surface igniters. While each works differently, they both do the same thing: ignite the gas in your furnace. When the igniter is dirty, has a crack, or there is no spark, the burners won’t light.
- Problems with the manifold – the burners are fed the gas via a manifold. The manifold is a pipe that runs the length of the burner, with small nozzles feeding gas into the burner tubes. If something obstructs the manifold from the inside, or the manifold is bent, problems can ensue with the burner, in addition to potential problems with safety.
Without a properly working burner, you may lose heating in your home. Repairing a burner is not a DIY kind of job, so call Command A/C and let one of our certified technicians handle any heating repairs in Cypress, CA.
