Common Sub-Zero Error Codes
Is your Sub-Zero appliance displaying an error code? Find out what it means and how our Toronto technicians can help.
Refrigerator Error Codes
| Error Code | Meaning | Description & Solution |
|---|---|---|
| EC 20 | Refrigerator defrost under-heat. | The defrost circuit is not reaching the expected temperature, allowing frost to build on the evaporator. The defrost heater, terminator, or sensor needs testing. |
| EC 21 | Refrigerator defrost over-heat. | The defrost heater exceeded the safe temperature limit. The defrost terminator or sensor has failed and must be replaced before the evaporator is damaged. |
| EC 24 | Refrigerator defrost fault. | The defrost cycle did not complete correctly. The defrost heater, terminator, and control board need diagnosis. |
| EC 05 | Refrigerator thermistor fault. | A refrigerator compartment thermistor is open or shorted. The sensor and wiring need testing and replacement. |
Freezer Error Codes
| Error Code | Meaning | Description & Solution |
|---|---|---|
| EC 06 | Freezer thermistor fault. | A freezer compartment thermistor is open or shorted. The sensor and wiring need testing and replacement. |
Other Error Codes
| Error Code | Meaning | Description & Solution |
|---|---|---|
| EC 50 | Excessive refrigerator compressor run time. | The refrigerator compressor is running far longer than normal, usually indicating a sealed-system or airflow problem. Check door seals and condenser cleanliness first; if the code persists the sealed system needs professional diagnosis. |
| EC 40 | Excessive freezer compressor run time. | The freezer compressor is running continuously without reaching target temperature. Clean the condenser and verify door seals; if the code persists the sealed system may have a refrigerant leak or compressor issue. |
| EC 15 | Sealed system / valve fault. | The control detected a sealed-system or refrigerant-distribution problem. This requires a sealed-system certified technician to diagnose refrigerant charge, the compressor, and the evaporator. |
| SERVICE | Service indicator flashing with temperature display. | The unit is reporting a fault that needs attention. Note any EC code shown alongside and book service. Do not power-cycle to clear without addressing the underlying issue. |
| Vacuum Condenser | Condenser cleaning required. | The unit detects reduced airflow across the condenser coil, usually from dust and lint buildup. Clean the condenser with a soft brush and vacuum; if the message returns after cleaning, the condenser fan or sensor may need service. This is one of the most common Sub-Zero calls. |
| LO | Low temperature alarm. | The compartment temperature has risen above the safe range. Check for door-ajar conditions and warm-item loading; if the alarm persists after the doors are closed the cooling system needs service. |
| HI | High temperature alarm. | The compartment is too warm. Verify the doors are fully closed and nothing blocks the vents. If the alarm continues, the sealed system or defrost circuit needs diagnosis. |
| ICE / No Ice | Ice maker fault indicator. | The ice maker is not producing ice. Check the water supply and filter first; if water is flowing the ice maker assembly, water valve, or optics need diagnosis. |
