Lo
Frigidaire Refrigerator
Severity: MinorWhat Does This Error Mean?
Lo means your Frigidaire refrigerator is detecting an unusually low temperature. This can happen in cold rooms or garages in winter. It can also mean the temperature sensor is faulty.
Affected Models
- Frigidaire FFSS2615TS
- Frigidaire FRSS2623AS
- Frigidaire Gallery FGHS2631PF
- Frigidaire Professional FPHS2687KF
Common Causes
- The refrigerator is installed in a very cold room, garage, or basement
- Ambient room temperature has dropped below the fridge's operating range
- Temperature control dial or setting was turned too cold accidentally
- Temperature sensor (thermistor) is faulty and giving incorrect readings
- Control board malfunction causing incorrect temperature regulation
How to Fix It
-
Check the room temperature where the refrigerator is installed.
Frigidaire refrigerators are typically designed for rooms between 55–110°F (13–43°C).
-
Check your temperature settings on the control panel.
Make sure the fridge isn't accidentally set to its maximum coldness level.
-
If the fridge is in a garage or cold area, consider moving it to a warmer location.
Cold ambient temperatures can confuse the thermostat and cause Lo alerts in winter.
-
Press any button to acknowledge the alert, then monitor temperatures for a few hours.
If the room is warm and the setting is correct, a sensor fault may be to blame.
-
If Lo continues in a normally heated room, call a technician to test the thermistor.
A replacement thermistor is a relatively inexpensive repair.
When to Call a Professional
If Lo appears in a normally heated room and the setting hasn't changed, call a technician. A faulty thermistor or control board will need professional diagnosis.
Frequently Asked Questions
Can Lo damage my food?
Extremely low temperatures can freeze food in the fridge compartment. Frozen lettuce, produce, and eggs can be ruined. Adjust the temperature setting or address the cause promptly.
Is Lo the opposite of Hi?
Yes — Hi means too warm, Lo means too cold. Both alerts mean the temperature is outside the normal safe range. Normal fridge temperature is 35–38°F (2–3°C).
Why does my garage fridge show Lo in winter?
Garage refrigerators are exposed to outside temperatures. In winter, the ambient temperature can drop below the fridge's minimum operating range. Consider a garage-rated refrigerator designed to work in colder environments.
