5-4. LEV
1. Function
1) The LEV lowers the pressure of the refrigerant so that the refrigerant can evaporate
easily from the evaporator, improving the refrigerant efficiency.
2) It adjusts the amount of refrigerant that flows into the evaporator.
2. Precautions
1) If the LEV is deformed due to the heat generated from the welding of LEV to the as-
sembly, the LEV may not work properly in the Drying and Refresh modes. Check if
there is any discoloration in the brass part within 5 mm from the body.
2) If the external impact was applied to the product or foreign substances have entered
the product, the properties of the LEV may change, leading to the malfunction of the
product in the Drying and Refresh modes. This problem, however, cannot be detected
with eyes.
3. Potential Failures
1) Clothes not dried or partially dried: Deformation inside the LEV due to welding or ex-
ternal impact
2) The component does not work: If the orifice is clogged due to foreign substances,
overload is applied to the component.
4. Things to Check in Case of Failure
1) Deformation inside the product due to the welding: Make sure that there is no discol-
oration in the brass part within 5 mm from the body and that the label on the body has
not burned.
2) If the motor is faulty, measure the resistance. The resistance should be 46 ± 3.7 Ω.
※ Measure the resistance between the Red_Com wire and each phase (select one
from white, orange, yellow, and blue).
※ You can check the properties of the component only using the flowmeter.
