How to Fix Frigidaire Refrigerator Error LO

Error Code: LO Difficulty: Easy

Problem: Low Temperature Alarm

How to Fix LO Error (Step-by-Step)

1. First, confirm that both the refrigerator and freezer doors are completely shut. Check for any items inside that might be preventing a tight seal.
2. 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.
3. 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.
4. 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.
5. 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.
6. After trying all steps, press the ‘Alarm Reset’ or ‘OK’ button on the control panel to silence the alarm and clear the code.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
