Error Code: LO Difficulty: Easy
Problem: Low Temperature Alarm
How to Fix LO Error (Step-by-Step)
- First, confirm that both the refrigerator and freezer doors are completely shut. Check for any items inside that might be preventing a tight seal.
- Inspect the rubber door gaskets for any tears, dirt, or debris. Clean the gaskets with warm, soapy water and a cloth to ensure they seal properly.
- Check the air vents inside both the freezer and fresh food compartments. Make sure they are not blocked by food packages, as this restricts cold air circulation.
- If you have recently loaded a large amount of warm groceries or experienced a power outage, the alarm may sound until the unit cools back down. Allow 4-6 hours for the temperature to stabilize.
- If the alarm continues after these checks, the temperature sensor (thermistor) may have failed. Unplug the unit, locate the sensor inside the fresh food section (usually a small plastic dome on the wall or ceiling), and replace it.
- After trying all steps, press the ‘Alarm Reset’ or ‘OK’ button on the control panel to silence the alarm and clear the code.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
