| Issue | What a technician checks on Lennox systems |
|---|---|
| AC not cooling | Capacitor, contactor, or low refrigerant; variable-speed Signature units need a Lennox-savvy diagnosis |
| Furnace short cycling / no heat | Flame-sensor buildup, pressure-switch or limit-switch trip on high-efficiency models |
| Long wait for a part | Proprietary parts are dealer-distributed — a Lennox-sourcing tech avoids delays |
| Fault LED flashing | Control board blinks a code; meaning varies by model |
| System underperforming | High-efficiency units must be sized and charged correctly to hit rated SEER/AFUE |
Tip: when a Lennox system flashes a fault light, note the blink pattern and your model number before you call — it speeds the diagnosis.
