Why is there a layer of ice on the coil of my WOODS LD48PRO+/LD44/LD40 dehumidifier and how can I fix it?

Question

Accepted Answer

The formation of ice on the coil of your WOODS LD48PRO+/LD44/LD40 dehumidifier is generally caused by insufficient air circulation or a room temperature that is too low. The main reasons are a clogged air filter that reduces airflow, a room temperature below 2°C (minimum operating limit), the unit being too close to a wall or obstacles (recommendation: at least 20-30 cm), or an extremely high humidity level that causes the compressor to run continuously.

Your unit is equipped with an automatic defrosting system i-EcoDefrost that naturally manages this issue. When the system detects ice buildup, it automatically shuts off the compressor and continues to run the fan. The ambient air then passes through the cooled coils, causing the ice to melt. During this cycle, the compressor temporarily stops, which is normal operation. Wait about 30 minutes before checking if the defrost cycle is complete.

To prevent excessive ice formation, first check that the air filter is clean and that air circulates freely. Place the unit at least 20-30 cm away from walls and obstacles to ensure good air circulation. Make sure the room temperature stays between +2°C and +35°C (the normal operating range). If the temperature drops below 2°C, use a specific anti-freeze cover to protect the unit.

If you detect a thick layer of ice on the cooling coils behind the filter, you can assist with defrosting: turn off the unit, let it sit for 30 minutes at room temperature, then restart it. Never attempt to scrape the ice yourself or use mechanical devices to speed up defrosting, as this could damage the cooling circuit. Under normal conditions, with a clean filter and good air circulation, the i-EcoDefrost system manages defrosting automatically without intervention.
