What Does Error EC Mean?

The EC error code on your Westinghouse Air Conditioner indicates a potential compressor failure, often triggered by a refrigerant leak or low refrigerant levels. This issue may cause the unit to run briefly before shutting down, poor cooling performance, and unusual humming sounds. A protective mode may activate to prevent further damage to the compressor, suggesting airflow issues or a malfunctioning system.

Common Symptoms:

  • Unit runs briefly then shuts down
  • Poor cooling performance
  • Error code EC displayed

Possible Causes

  • Refrigerant leak or low refrigerant level detected (medium)
  • Protective shutdown due to system not performing (possibly filter or airflow issues leading to false detection) (low)

How to Fix Error EC

DIY Fix Basic user checks for EC error

  1. Turn off the air conditioner and disconnect power for several minutes.
  2. Check/clean air filters and ensure good airflow.
  3. Visually inspect for obvious signs of refrigerant leak on lines or connections (oil residue).
  4. Restart the unit after power-down to see if the code clears.

Technician Only Technician diagnosis and repair for EC error

  1. Use HVAC gauges or leak detectors to check refrigerant pressure and locate possible leaks.
  2. Repair any identified refrigerant leak and perform proper refrigerant recharge to manufacturer specifications.
  3. Inspect and test pressure sensors and control board for correct operation.
  4. Check airflow, filters, and outdoor unit clearance; ensure proper airflow to avoid false low-pressure signals.

Parts needed: Refrigerant (R410A or unit-specific type), Pressure sensors, Control board, Seals/lines at leak location

🛑 When to Call a Pro:
  • If EC error persists after filter cleaning and power reset
  • If there is visible refrigerant leakage
  • If cooling performance is poor or unit repeatedly shuts down
