Signs Your System Needs an Ignitor Replacement
Furnace Clicks But Won't Ignite
You can hear the furnace trying to start, but the burners never kick on. This is the number one sign of a bad ignitor.
Blower Runs But Air is Cold
The fan is circulating air through your home, but it's just room-temperature air, not heated air, because the furnace never lit.
System Shuts Down Quickly
The furnace will try to light a few times, and when it fails, the control board will shut the system down for safety. If your furnace ain't working right and gives up after a minute or two, it's often the ignitor.
No Glow from the Ignitor
On many furnaces, you can look through a small viewport and see the ignitor glow bright orange like a lightbulb filament. If you don't see that glow, the ignitor is dead.

Deep Dive: What is a Furnace Ignitor?
A furnace ignitor is a small, simple part that gets incredibly hot to ignite the gas in your furnace's burners. Think of it as the modern replacement for an old-school pilot light. It's made of a very brittle material called silicon carbide, which is why they are so fragile and a common point of failure.
Pro-Tip: Never touch a furnace ignitor with your bare hands. The oils from your skin can cause the ignitor to burn out prematurely once it's installed.
Deep Dive: Testing the Ignitor for Continuity
To be certain the ignitor is the problem, we use a multimeter to test for continuity. A good ignitor will have a specific electrical resistance reading. A worn out or cracked ignitor will show an open circuit (no continuity), meaning electricity can't pass through it to generate heat. This is a definitive test that tells us the part is bad.
Pro-Tip: Even if an ignitor isn't completely dead, its resistance can change over time, causing it to not get hot enough to reliably light the gas. We recommend replacing it if it's out of spec.
Why Tampa's Climate Wrecks Ignitors
It might seem strange that our climate affects a furnace part, but the high humidity in Tampa plays a role. Moisture can lead to corrosion on the electrical terminals that connect to the ignitor. More importantly, because our furnaces sit unused for most of the year, the ignitor is subject to long periods of inactivity followed by sudden, intense use, which can be stressful for the fragile component. Power surges from our frequent thunderstorms can also easily burn out an ignitor.
Check This Before You Call
If your furnace isn't lighting, the first thing to do is make sure your air filter is clean. A severely clogged filter can restrict airflow and cause the furnace to overheat and shut down as a safety measure. While you have the filter out, you can often peek inside the unit to see if the ignitor glows when the furnace tries to start. If you see no glow, you've found your problem.
