| What you're seeing | Likely causes a technician checks |
|---|---|
| Furnace won't turn on | Tripped breaker, thermostat fault, blown fuse, bad control board, safety lockout |
| Blows cold air | Dirty flame sensor, failed igniter, out of gas/pilot, oversized cycling |
| Short cycling | Overheating from dirty filter, bad flame sensor, blocked vent, limit-switch trip |
| Clicks but won't ignite | Failed hot-surface igniter, dirty/cracked flame sensor, gas valve, pressure switch |
| Loud bang on startup | Delayed ignition from dirty burners — have it checked promptly |
| Blower runs constantly | Thermostat set to 'fan on', failed fan limit switch, control board |
