Dehumidifier displays LO and does not start dehumidifying

Note: LO is usually an informational protection code, not a hardware fault.

• Measure room temperature: If the room is below about 5–10°C, move the unit to a warmer area or heat the space.
• Allow unit to warm: If the unit was stored in a cold area, bring it indoors and let it sit unplugged for several hours to reach room temperature before use.
• Sensor check: If LO appears even in a warm room, inspect and test the ambient NTC sensor and replace if it reads abnormally low.
