7. Troubleshooting
Many furnace issues can be complex and require professional diagnosis. The following are general troubleshooting tips. Always disconnect power before inspecting components.
| Symptom | Possible Cause | Action |
|---|---|---|
| Furnace not starting | No power, thermostat issue, safety limit open, faulty board. | Check power supply, thermostat settings. Consult a technician for limit switch or board diagnosis. |
| Burners not igniting | No gas, faulty igniter, dirty flame sensor, faulty board. | Ensure gas supply is on. Clean flame sensor. If issues persist, contact a technician. |
| Blower not running | Faulty blower motor, capacitor, or control board. | Contact a qualified technician for diagnosis and repair. |
