What Is the Furnace Ignitor?
The furnace ignitor is a component that ignites the fuel source (in gas furnaces) or the heating element (in electric furnaces). In older heating systems, the process uses a pilot light. In newer models, it employs an electric method for heating.
Do you hear a click when the gas furnace activates? That’s the ignitor releasing a spark to set the fuel aflame.
Other processes simply use electrical current to heat a coil. The air passes over the component and becomes warm before circulating through the home.
Signs You Have Bad Ignition Components in Franklin
How can someone tell when furnaces have pilot light issues and need igniter repairs?
Cold Air Blows From the Vents
When a furnace blows cold air, assume it can’t properly heat the air passing through it. While multiple problems could cause the issue, a faulty ignitor is one of the most common.
Examine the thermostat setting and ensure no one set it to heating mode rather than “cool” or “auto.” Also, check the air filter. When it builds up dirt, it can restrict airflow and cause it to lose heat.
If neither solution works, you may have a spark failure from the ignitor or a related issue. Only a certified expert in Franklin can discern the true problem.
The Furnace Doesn’t Turn On
When homeowners have trouble with a furnace not lighting, they sometimes report the device won’t even activate. This could occur from a bad ignitor in a furnace.
First, check the circuit breaker to determine whether it lost power. Then, ensure the thermostat isn’t causing the issue. If neither indicates a problem, that doesn’t necessarily mean the device has ignition troubles.
Call an HVAC technician to diagnose and fix the issue. Whether you have an electrical problem or a broken component, they can help.
Intermittent Failure and Deactivation
A furnace that never turns on isn’t the only type of electrical issue a heating system can experience. If the system stops blowing in the middle of a cycle, the safety feature may have kicked in. First, perform the routine checks, such as examining the air filter and thermostat.
Another common problem includes a phenomenon called rapid cycle. This occurs when the heating system quickly switches between turning off and on. Finally, a frequently tripping circuit breaker indicates a serious concern rooted in your device’s electrical connections.
If you believe the ignitor isn’t obtaining the power it needs, never attempt a DIY repair. Only a trained and certified Franklin HVAC expert should address such complicated solutions.
Nothing Happens After the Click
A bad ignitor in a furnace may still click on as it releases a spark, but if the next part of the process fails, nothing further occurs. In a gas ignition device, this is a dangerous problem that could allow excess gas into the home. If the system doesn’t start blowing after the click, shut everything off and call for repairs.
Tips for Preventing Furnace Issues
Every heating system needs repairs eventually. However, when homeowners take precautions, they significantly reduce the frequency and severity of problems.
Prioritize Annual Maintenance
Schedule a system tune-up at least once a year. Many Franklin homeowners prefer to do it in the late fall, so they know the device will make it through the winter without issue.
During maintenance, the HVAC technician inspects every component and makes minor adjustments that keep the device running efficiently. They’ll also notice minor issues before they cause serious problems. Don’t underestimate how much money you save with this habit.
Moderate Heating System Usage
Wear and tear is a major cause of furnace problems. The more a home uses it, the sooner it needs repairs.
The United States Department of Energy suggests keeping the thermostat at 68 degrees in the winter. Add blankets and drink warm beverages to increase comfort.
