Troubleshooting common Trane furnace problems

When your Trane furnace isn’t performing as expected, these resources can help you diagnose and resolve the issue:

  • Why won’t my furnace ignite?
    If your furnace isn’t igniting, it could be due to a faulty gas valve, a dirty burner orifice, or a damaged flame sensor. Check out our guide on Why your furnace won’t ignite for step-by-step troubleshooting.

  • Why isn’t my furnace blowing hot enough?
    A clogged air filter or a malfunctioning thermostat can reduce your furnace’s heating efficiency. Learn more with our guide on Why your furnace isn’t blowing hot enough.

  • Why won’t my furnace turn on?
    If your furnace won’t start, the issue could stem from an electrical problem, a faulty thermostat, or a gas supply issue. Visit our guide on Why your furnace won’t turn on.

  • Why won’t the furnace burners stay lit?
    Burners that won’t stay lit could indicate a dirty flame sensor or a faulty gas valve. For more details, check out our guide on Why furnace burners won’t stay lit.

  • How to replace the furnace flame sensor.
    The flame sensor detects the burner flame and signals the gas valve to stay open. Follow our guide on How to replace the furnace flame sensor to keep your furnace running safely and efficiently.
