Do you have a question about the LRTLS2403S / 00 and is the answer not in the manual?
Questions and answers
Model LRTLS2403S not staying on the coldest setting. We have the fridge in a clinical setting and need tight temperature control. When I hold the temperature adjust button and then click it to the coldest setting, it will later revert back to having only the last 3 lights green and first 2-3 off. This is too warm and is setting off our alarms.
The LG LRTLS2403S refrigerator may not be maintaining the coldest temperature setting due to several possible reasons:
1. Blocked Air Vents – If the air vents are blocked, cold air cannot circulate properly.
2. Frequent Door Openings – Opening the doors often allows warm ambient air inside, affecting the temperature.
3. Improper Door Closure – If the doors are not closing properly, cold air escapes, preventing the refrigerator from maintaining the set temperature.
4. Incorrect Control Settings – If the temperature settings are too high, the refrigerator will not stay as cold as desired.
5. Sensor Issues – A faulty temperature sensor or loose connection in CON8 could affect temperature regulation.
Solutions include ensuring air vents are clear, minimizing door openings, checking door seals, adjusting temperature settings incrementally, and verifying sensor connections.
