Furnace Flame Sensors

Flame sensors offer significant benefits in HVAC systems by enhancing both safety and efficiency. They accurately detect the presence or absence of a flame in your furnace, preventing the release of unburned gas.

These sensors ensure your furnace operates at optimal efficiency by assisting in regulating the ignition process.

At Furnace Part Source, we provide a wide selection of high quality HVAC parts and equipment, including flame sensors. Continue reading to learn why flame sensors are such a crucial component of your HVAC system.

-split-

What Is A Flame Sensor For?

A flame sensor is an indispensable component of your furnace. It confirms the presence of a flame when your furnace ignites, and it shuts off the gas supply if no flame is detected, preventing the potential hazard of gas buildup. Besides, the flame sensor works closely with the ignitor, monitoring its performance for efficient system operation.

When Does Your Furnace Flame Sensor Need Replacement?

Signs that your flame sensor may need attention include frequent system shutdowns, a furnace that won't stay on, or the flame failing to ignite at all

You will find the flame sensor generally outside the burner assembly. After turning off the power and closing the gas valve, you can safely remove it to examine more closely. This will help you determine if you have a dirty flame sensor or a broken one. In some cases, a good quality sensor can simply be cleaned to restore the original functionality.

A flame sensor tends to have porcelain insulation. If this porcelain is severely damaged or missing a few pieces, then it’s also a sign to make a replacement.

How Often Should You Expect To Replace Your Flame Sensor?

While flame sensors are relatively durable, they should ideally be checked annually as part of regular maintenance. If you've recently replaced your flame sensor, it's reasonable to expect it to last for a few years without issue. However, the lifespan can vary depending on the furnace usage and the quality of the part, so regular inspections are key.

How To Maintain Your Flame Sensor?

Cleaning some portions of your HVAC system regularly is necessary. Debris can make its way into almost every portion of the equipment over time. That’s especially a problem for commercial operations that are designed to heat large areas of physical space.

Cleaning a furnace sensor is pretty straightforward. Once you have removed the flame sensor from the furnace and turned off all power and gas, start wiping it down with a fine emery cloth. You should have a smooth surface when you’re done with no strong marks or remaining materials that could create the right kind of conditions for a clog.

Make sure to remove all of the debris before you consider reinstalling it. Fortunately, finished porcelain is a relatively slick substance, so this shouldn’t normally be difficult.

Find High Quality Flame Sensors At Furnace Part Source

Flame sensors play a critical role in your HVAC system. They require regular maintenance to keep working properly and may even need to be replaced every few years.

At Furnace Part Source, we pay attention to the details to make sure you get the most out of your HVAC system..

HVAC components can be overwhelming. But, our team of experts is here to help you find the perfect fit for your furnace. Reach out to us today to get started.
