Furnace Ignitor Not Working Fix
If your furnace is not igniting, it often points to an issue with the furnace ignitor. A faulty furnace ignitor can cause your heating system to fail, leaving your home cold. Fortunately, fixing a furnace ignitor not working issue is often straightforward when using reliable OEM HVAC parts and the right tools.
Common Causes of Furnace Ignitor Failure
Understanding why your furnace ignitor is not working helps you diagnose and fix the problem quickly. Common causes include:
- Wear and Tear: Ignitors degrade over time due to heat cycles.
- Electrical Issues: Loose wiring or faulty connections can prevent ignitor operation.
- Dirt and Debris: Dust accumulation can interfere with ignitor function.

- Physical Damage: Cracks or breaks in the ignitor element.
How to Fix a Furnace Ignitor Not Working
Follow these step-by-step instructions to troubleshoot and fix your furnace ignitor issue:
1. Turn Off Power to the Furnace
Ensure your safety by switching off the furnace’s power at the breaker panel before performing any repairs.
2. Inspect the Furnace Ignitor
- Locate the ignitor; it’s typically near the burners.
- Check for visible damage such as cracks or broken pieces.
- Look for signs of dirt or soot buildup.
3. Test the Ignitor
Use a multimeter to check the ignitor’s resistance. A reading outside the manufacturer’s specifications usually means the ignitor needs replacement. For more precise testing, consider using professional HVAC tools.
4. Replace the Furnace Ignitor
- Order an OEM replacement ignitor compatible with your furnace brand. For example, you can find parts for popular brands like MRCOOL.
- Carefully remove the faulty ignitor and install the new one following your furnace’s manual.

5. Restore Power and Test
Turn the power back on and run your furnace. The ignitor should now glow and ignite the burners properly.
