Display shows LO or Low; temperature setpoints may be at minimum; unit may run excessively cold.

Safety first: No internal electrical work is required for basic checks. If accessing boards, unplug the unit first.

Step 1 – Verify temperature settings:

• Check the control panel and confirm the set temperatures for fresh food and freezer.
• Adjust to recommended settings (typically 37°F / 3°C for fresh food and 0°F / -18°C for freezer).

Step 2 – Check for special modes:

• Ensure the unit is not in Sabbath mode or demo mode, which can alter display behavior.
• Refer to the user manual to exit any special modes.

Step 3 – Confirm actual temperatures:

• Use thermometers in both compartments to verify real temperatures.
• If actual temperatures are normal despite LO display, the issue may be cosmetic (display/UI).

Step 4 – Reset control electronics:

• Unplug the refrigerator for 5 minutes, then restore power.
• Re-enter desired temperature settings.

Step 5 – Sensor or board issues:

• If temperatures are too cold and do not respond to setting changes, test thermistors and inspect the main control board as described in other temperature fault entries.

When to call a technician: If LO persists with abnormal temperatures after reset and sensor checks, professional diagnostics are advised.
