Questions and answers
Top up gas 7yrs already..ice cube not solid
To fix the issue of ice cubes not solidifying in the Whirlpool refrigerator model 7S21FNI SL after 7 years of use, follow these steps:
1. Check Freezer Temperature – Ensure the freezer is set to the correct temperature (typically around -18°C or 0°F).
2. Inspect Freezer Door Seal – Make sure the door seal is intact and closing properly to prevent warm air from entering.
3. Verify Airflow – Ensure that vents inside the freezer are not blocked by food items, allowing proper cold air circulation.
4. Check for Frost Buildup – If there is excessive frost, the defrost system may not be working properly. Inspect the defrost sensor (E9 fault code may indicate failure).
5. Inspect Evaporator Fan – If the fan is not running, cold air may not be circulating properly. Replace if faulty.
6. Ensure Compressor is Functioning – If the compressor is frequently tripping, check for refrigerant leaks or an issue with the overload protection device.
7. Power Supply Check – Ensure the refrigerator is receiving stable voltage as fluctuations can affect cooling performance.
8. Clean Condenser Coils – Dust buildup can reduce cooling efficiency; clean the coils regularly.
9. Check Ice Maker Operation – If using an automatic ice maker, ensure the water supply is functioning properly.
If the issue persists, consider consulting a professional technician for further diagnosis.
