5-3. Main Fan
1. Function
1) Drying: It supplies the air that was heated by heat exchanger into the product and cir-
culates it to dry the clothes that are wet.
2. Precautions
1) When the water penetrates into the motor, noise may occur.
2) The product may be damaged due to external impact such as vibration and overload.
3. Potential Failures
1) Noise: Noise may occur due to the friction between impeller and housing or due to the
internal bearing damaged by vibration or overload.
2) The component does not work: The component is not fully inserted into the housing.
3) The fan movement is restricted: There is interference between parts (If any of the
tightening screws is missing on the impeller, the impeller may shake, interfering with sur-
rounding parts).
4. Things to Check in Case of Failure
1) Check the Precautions section first and figure out the cause of failure.
2) If the motor is faulty, measure the coil resistance. The resistance should be 29 ± 5 %
(75 ℃).
