Common Gas Furnace Problems and What Causes Them
Read the Symptoms
Common gas furnace problems follow a pattern. What the furnace does when it tries to start usually tells a tech where to look first.
| Symptom | Likely Cause | Typical Fix |
|---|---|---|
| Lights, then shuts off in seconds | Dirty flame sensor | Clean or replace sensor |
| Clicks, never lights | Cracked ignitor or gas valve | Replace ignitor or valve |
| Hum or rattle, then shuts down | Draft inducer motor | Replace inducer |
| Inducer runs, nothing else | Pressure switch or blocked vent | Replace switch, clear vent |
| Blows cold air | Gas off, ignition problem, limit switch | Diagnose and repair |
| Blinking light code | Control board reporting a fault | Read code, fix cause |
| Short cycling | Dirty filter, limit switch, oversized furnace | Airflow fix or repair |
What Do the Blinking Lights on My Furnace Mean?
The blinking lights on your furnace are a diagnostic code from the control board. Count the blinks and match them to the chart inside the furnace door.
- Common codes point to flame sensing, pressure switch, limit switch or ignition faults.
- The code narrows the problem, but a tech still tests the part.
- Write down the blink pattern before you call.

Why Gas Furnaces Fail in Lowcountry Homes
Damp, Dust, Downtime
Gas furnaces in Lowcountry homes often fail from moisture, dust and long stretches of not running. Furnaces in crawl spaces and garages sit idle all summer in humid air.
- Humidity: rusts burners and corrodes sensors.
- Long idle months: dust and spiders settle in the burners.
- Dirty filters: overheat the heat exchanger.
- Crawl space installs: damp air and pests.
- Skipped tune-ups: small problems grow.
