Display shows L1 or LO and temperature appears too cold or below setpoint.

Safety: Adjustments to settings are safe with power on. Unplug the unit before opening any panels.

Steps to address L1/LO:

• Check set temperature: Verify the setpoint on the display. Increase the set temperature a few degrees (warmer) and monitor.
• Check sensor placement: Ensure the interior temperature sensor is not touching the evaporator coil directly or buried in frozen food, which can cause incorrect readings.
• Observe compressor run time: If the compressor runs almost continuously even after raising the setpoint, the control board relay may be stuck closed.
• Power reset: Unplug the freezer for 5–10 minutes, then plug back in to see if the alarm clears and control responds normally.
• Inspect control board (if needed): If the unit continues to overcool, access the main PCB and look for welded or burnt compressor relay contacts. Replacement of the board is usually required.

Note: Prolonged overfreezing can damage stored food containers and increase energy use. Address persistent low temperature alarms promptly.
