Possible Causes

Low refrigerant charge due to leak, Blocked capillary tube or expansion device, Severely dirty evaporator coil, Faulty low-pressure sensor or thermistor

How to Fix / Troubleshooting

Safety first: Unplug the unit before removing covers. Refrigerant handling must be done by a certified technician.

  • 1. Clean coils and filter:
    • Remove and clean the air filter.
    • Vacuum dust from the evaporator and condenser coils.
  • 2. Check ambient conditions:
    • Ensure the room temperature is within the operating range specified by Crane (typically above 41°F/5°C).
    • Very low room temperatures can trigger EC on some models.
  • 3. Inspect for icing:
    • Look at the evaporator coil while running; heavy ice buildup can indicate airflow or refrigerant issues.
  • 4. Sensor check:
    • Locate the low-pressure or evaporator temperature sensor and ensure it is properly clipped to the coil and wired.
  • 5. Professional diagnosis:
    • If EC persists after cleaning and verifying sensors, the sealed system likely has a leak or restriction.
    • Contact a refrigeration technician for leak detection, evacuation, and recharge or coil replacement.
