What It Means
Low Pressure / Low Ambient
Likely Causes
- Ambient air temperature below 50°F (normal cutoff)
- Low refrigerant charge
- Dirty evaporator coil (reduced airflow)
- Refrigerant leak
Next Checks
- Check ambient temp — below 50°F is normal shutdown
- Clean evaporator coil fins with garden hose (spray outward)
- If ambient is warm and code persists: refrigerant issue — call HVAC tech
