Dehumidifier display shows LO and unit does not dehumidify

Safety first: No internal work is required for basic checks, but unplug the unit if you move it or open panels.

• Step 1 – Check room temperature: Use a separate thermometer to verify the room is above 5–10°C (41–50°F). Danby dehumidifiers will not run below their minimum temperature and will show LO.
• Step 2 – Relocate unit: Move the dehumidifier away from cold concrete floors, exterior doors, or unheated areas. Elevating the unit on a small platform can reduce exposure to cold drafts.
• Step 3 – Allow warm-up: If the unit was stored in a cold area, bring it into a warmer room and let it sit unplugged for 2–3 hours before use.
• Step 4 – Sensor check (advanced): If the room is clearly warm but LO remains, the ambient thermistor may be faulty. Inspect and test it as described for E1 errors.

When to call a technician: If LO displays in a warm environment and a new ambient sensor does not resolve it, the control board may need replacement.
