Why Is My Furnace Not Igniting?

- Failed hot-surface igniter: The igniter may crack or stop producing sufficient heat.
- Dirty flame sensor: The burner may ignite briefly before the furnace shuts itself down because the sensor does not detect a proper flame.
- Thermostat problems: Incorrect settings, weak batteries, wiring issues, or a malfunctioning thermostat can prevent a heating cycle.
- Dirty air filter: Severe airflow restriction can cause overheating and trigger safety controls.
- Gas-supply problems: A closed valve or supply interruption can prevent ignition.
- Blocked intake or exhaust: High-efficiency furnaces require unobstructed venting.
- Faulty control board: An electrical or control problem can interrupt the ignition sequence.
What to Check Before Calling for Furnace Repair
Some basic checks are safe for homeowners and can identify an easy-to-correct problem.Step 1: Check the thermostat
Set the thermostat to HEAT and raise the temperature several degrees above the current room temperature. If it uses batteries, replace them if they are weak.If the thermostat appears normal but the furnace remains inactive, call

A heavily clogged filter can restrict airflow and contribute to furnace shutdowns. If the filter is visibly dirty, replace it with the correct size and type recommended for your system.Step 3: Check the furnace power
Make sure the furnace service switch has not been accidentally turned off and that the electrical breaker has not tripped.Do not repeatedly reset a breaker that continues to trip. That can indicate an electrical fault requiring professional attention.
Step 4: Look for an error code
Many modern furnaces have an LED diagnostic light. The manufacturer's panel may provide a code chart explaining what a particular blinking pattern means.Don't remove safety panels or attempt electrical repairs yourself. For furnace diagnostic assistance, contact

Other possibilities include:
- Burner contamination

- Weak ignition
- Faulty flame sensor
- Venting problems
