5. Self Diagnosis & Trouble Shooting
5-8. When the Fan does not operate (F, R, M, C - FAN)
- This refrigerator uses the BLDC Fan Motor. The BLDC Motor operates with DC 7~12V.
- Under Comp On conditions, the R-Fan operates generally. But, when the ambient temperature is high or when
you open and close the Door once, it operates after one-minute delay. So, don't get misled by it. It is normal.
- When there is defect, turn on the Self-Diagnosis function and confirm the defect before turning off the
unit.
