When temperatures drop, you expect your heating system to keep your home comfortable. But if your furnace starts and stops without producing heat, or fails to turn on altogether, an ignition problem may be the cause.
Understanding the warning signs can help you recognize when your furnace needs professional attention.
Common Signs of Furnace Ignition Trouble
A furnace may experience ignition issues for several reasons. You might hear the system attempt to start without producing warm air, notice repeated clicking, or find that the furnace shuts down shortly after starting.
Possible causes include a faulty ignitor, a problem with the gas supply, a malfunctioning flame sensor, or an issue with the system’s safety controls.
Because these components work together, the same symptom can have different causes. A professional diagnosis can help identify the actual problem.
What to Do When Your Furnace Won’t Ignite
Start by checking your thermostat to make sure it is set to heating and the temperature is above the current room temperature. You can also check whether the furnace’s power switch has been turned off.
If the furnace continues to fail, avoid repeatedly restarting it or attempting to repair gas or electrical components yourself.
If you smell gas, leave the building without operating electrical switches or using a phone inside. From a safe location, contact your gas utility or emergency services.
