Dehumidifier display shows LO and unit does not dehumidify

Safety: No internal work is required for basic checks; unplug before opening the unit.

Steps:

• Check room temperature: Verify the room is within the dehumidifier's operating range (typically above 41°F / 5°C). Move the unit to a warmer area if necessary.
• Avoid cold drafts: Do not place the unit directly in front of open windows, exterior doors, or unheated basements where localized cold air can affect the sensor.
• Reset: Unplug for 5 minutes, then plug back in. If LO remains despite a warm room, the ambient temperature sensor may be faulty.
• Sensor inspection: Refer to the E1 entry for locating and checking the ambient temperature sensor. Replace if it is misreading or damaged.
