Frigidaire Refrigerator Error Code LO

LO on a Frigidaire refrigerator indicates that the control panel lock feature is active. All buttons on the panel are disabled until the lock is cleared. This is a deliberate child lock or tamper prevention function, not an error or malfunction. No component has failed when this code appears.

No, the LO code does not indicate any safety issue. The refrigerator continues to run normally with the control lock active, maintaining its set temperatures and operating all internal systems. Only the control panel buttons are disabled, so food safety is not affected.

In almost all cases, clearing the LO code costs nothing because it is resolved by pressing the CONTROL LOCK button for 3 seconds. If the CONTROL LOCK button or user interface board is faulty and prevents unlocking, replacement parts and labor could range from roughly 100 to 300 dollars depending on the specific model and service rates in your area.

Press and hold the CONTROL LOCK button on the control panel for 3 seconds. The LO indicator should turn off and all buttons should become responsive again. If the display does not clear after holding the button, try unplugging the refrigerator for a few minutes and then attempting the unlock process again after restoring power.

Unplugging the refrigerator may or may not clear the LO code. Because the control lock state is stored in the control board's memory, it can persist through power interruptions and may return when power is restored. The correct method to clear LO is to press and hold the CONTROL LOCK button for 3 seconds while the unit is powered on.
