Why Your Furnace Won't Ignite
Modern furnaces rely on several components working together. If even one part fails, the ignition sequence may stop completely.Dirty Flame Sensor
One of the most common reasons a furnace won't stay running is a dirty flame sensor. When coated with dirt or oxidation, it cannot detect a flame, causing the furnace to shut off shortly after ignition.Cleaning or replacing the sensor often restores normal operation. If you're unsure how to inspect it safely, call
Faulty Hot Surface Igniter
Most newer furnaces use a hot surface igniter instead of a standing pilot light. These components naturally wear out over time.Signs include:
- Furnace blower runs without heat
- No visible glow from the igniter
- Repeated startup attempts
- Cold air from vents
Gas Supply Problems
No ignition can also indicate an interrupted gas supply. Potential causes include:- Closed gas valve
- Utility service interruption
- Faulty gas valve inside the furnace
- Low gas pressure
Signs Your Furnace Needs Immediate Attention
Your heating system often gives warning signs before complete failure.Watch for These Symptoms
- Furnace clicks but never starts
- Igniter glows without burner ignition
- Pilot light repeatedly goes out
- Short heating cycles
- Flashing diagnostic error codes
- Burning odors

- No warm air despite thermostat calling for heat
Step-by-Step Troubleshooting Before Calling
While many ignition problems require professional repair, homeowners can safely perform a few basic checks.Step 1: Verify Thermostat Settings
Ensure the thermostat is:- Set to Heat
