The dehumidifier display shows LO and the compressor fails to start.

Note: LO is typically an informational code indicating the room is too cold for normal operation.

• Measure room temperature: If below ~41–50°F (5–10°C), move the unit to a warmer area.
• Relocate away from cold sources: Do not place the unit directly on a cold floor or near open windows.
• Check ambient sensor placement: If accessible, ensure the ambient sensor is located in the air intake path, not touching cold metal surfaces.
• If LO appears in a warm room: Test and replace the ambient temperature sensor as described under E1.
