Dehumidifier displays LO and does not start dehumidifying

Note: LO is usually an informational code indicating the room is too cold for safe operation.

Steps:

• Check room temperature: Use a separate thermometer to verify the room is above the minimum operating temperature (typically 41–45°F / 5–7°C).
• Relocate unit: Move the dehumidifier to a warmer area away from exterior doors, windows, or unheated basements.
• Sensor check: If the room is warm but LO still shows, inspect the ambient temperature sensor and its wiring as described for E1. Replace if faulty.

Warning: Running a dehumidifier in very cold conditions can cause coil icing and damage; do not bypass LO protection.
