Dehumidifier display shows LO and unit does not dehumidify

Safety: No internal service is required for basic checks; unplug before opening the cabinet.

Steps:

• Check room temperature: Verify the room is within the specified operating range (typically above 5°C / 41°F). Move the unit to a warmer location if necessary.
• Avoid cold drafts: Do not place the dehumidifier directly on cold concrete or next to exterior doors/windows where the sensor may read lower than actual room temperature.
• Sensor check: If the room is warm but LO still shows, inspect and test the ambient temperature sensor as described under error E2. Replace if out of specification.
• Control board: If a new sensor does not resolve the LO indication, the main control PCB may be misreading temperature and should be replaced.
