Furnace Fan Works But No Heat? Here’s What It Means (And What to Do)

It’s a cold Nebraska morning, and your furnace fan is running—but your home still feels chilly. If your furnace fan works but there’s no heat, something’s off—and it’s not just the thermostat.

This is a common scenario we hear from homeowners needing furnace repair in Omaha. The good news? It doesn’t always mean a complete system failure. But it’s not something you want to ignore either.

What’s Going On?

If the blower is on but warm air isn’t coming through, here are a few possible causes:

• Faulty ignitor or pilot light: Your furnace may be trying to heat, but if the ignitor fails, no flame means no warmth.
  
  
• Thermostat issues: Sometimes, it’s as simple as incorrect settings or a thermostat that needs replacement.
  
  
• Clogged air filter: A dirty filter can restrict airflow, causing the furnace to overheat and shut down the burners.
  
  
• Tripped limit switch: This safety feature turns off the burners if the system overheats, while the fan continues to blow to cool things down.
  
  
• Old or failing system: If your furnace is 15 years old or older, this may be a sign that it’s nearing the end of its life.
  
  

Whatever the case, the smartest next step is to call Controlled Comfort for a diagnosis.
