Possible Causes

Refrigerant leak in evaporator or tubing, restricted capillary tube, weak compressor, sensor miscalibration causing false low-cooling detection

How to Fix / Troubleshooting

Safety First: Unplug the unit. Sealed system repairs require EPA-certified technicians and specialized tools.

User-level checks:

  • Ventilation: Ensure proper airflow around the unit and that the condenser coil and fan are clean and operating.
  • Ambient temperature: Confirm the unit is used within the specified temperature range.
  • Reset: Unplug for 10 minutes, then plug back in and monitor if the unit can complete a full cycle.

When to call a technician:

  • If the compressor runs continuously but the evaporator does not frost evenly.
  • If E13 returns repeatedly after basic checks.
  • If you see oily residue on tubing (sign of refrigerant leak).

A professional will check system pressures, locate leaks, evacuate, and recharge the system or replace the compressor/evaporator as needed.
