Danby refrigerator displays L1 or LO and the temperature reading flashes, indicating low temperature (overcooling).

Safety: Unplug the refrigerator before accessing sensors or control boards.

Steps to address L1/LO:

• Verify setpoints: Confirm that the temperature settings are not set too low. Adjust to recommended settings (e.g., 3–5°C / 37–41°F for fresh food, -18°C / 0°F for freezer).
• Check thermistors: A shorted thermistor can cause the control to think the compartment is warm and run the compressor excessively. Test the relevant compartment thermistor(s) for proper resistance at room temperature and replace if out of spec.
• Inspect air damper (if equipped): On some Danby models with a motorized damper between freezer and fresh food sections, ensure the damper is not stuck open. Replace the damper assembly if it does not move or is broken.
• Control board evaluation: If sensors and damper are good, the main control board may be misreading temperatures or keeping the compressor on too long. Board replacement may be required.
• Prevent food damage: Until the issue is resolved, move sensitive items (produce, beverages) to a different refrigerator or adjust settings higher to reduce freezing risk.
