E9

SMAD Low Refrigerant / Evaporator Frost Fault (Detected by Sensor Logic)

E9 is displayed and the ice maker stops; fan may run but no ice is produced.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Refrigerant leak in evaporator or tubing, restricted capillary tube, weak compressor, severe frost pattern abnormality detected by sensors

How to Fix / Troubleshooting

Safety: Refrigerant system repairs require certified technicians and specialized tools. Do not attempt to open the sealed system yourself.

User-level checks:

Ventilation: Ensure the unit has proper airflow around the condenser and that the fan is operating.
Ambient temperature: Confirm the ice maker is used within SMAD's specified ambient temperature range (typically 10–32°C). Extreme heat can trigger protection errors.
Power reset: Unplug for 10 minutes and restart. If E9 returns and the unit does not cool, a sealed system issue is likely.

When to call a technician:

If the compressor runs but the evaporator does not get uniformly cold or only a small section frosts.
If you hear hissing or see oil stains on tubing (signs of a leak).
In these cases, contact a qualified refrigeration technician to inspect the evaporator, capillary tube, and compressor and recharge or repair the system as needed.
