| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Furnace won't start | Power issue/thermostat | Check circuit breaker; verify thermostat settings; ensure gas valve open. |
| No heat production | Ignition failure | Check for spark at igniter; verify gas supply; inspect flame sensor. |
| Short cycling | Dirty filter/overheating | Replace air filter; check for blocked vents; verify proper airflow. |
| Blower not running | Motor issue/control | Check blower capacitor; verify control board signals; inspect motor. |
| Unusual noises | Mechanical issues | Inspect blower wheel; check for loose components; verify motor bearings. |
| Error codes displayed | System faults | Refer to diagnostic chart in service manual; reset system if safe. |
Reset Procedure: Turn power off for 30 seconds, then restore.
