Display shows LO and dehumidifier does not start dehumidifying

Safety: No internal work is required for normal LO operation.

Steps:

• Check room temperature: Use a thermometer to confirm the room is above the minimum temperature specified in the Sencor manual (often 5–7°C).
• Relocate unit: Move the dehumidifier away from cold windows, exterior doors, or unheated spaces.
• Sensor check: If LO appears in a warm room, test the ambient NTC sensor as described under E1 and replace if faulty.

Note: LO is often a normal indication, not a fault, when the room is too cold.
