8-1-13 Defrosting (removing frost)
1. Defrosting starts each time the COMPRESSOR running time reaches 7~50 hours.
2. For initial power on or for restoring power, defrosting starts when the compressor running time reaches 4 hours.
3. Defrosting stops if the sensor temperature reaches 46°F(8°C) or more. If the sensor doesn't reach 46°F(8°C) in
1 hours, the defrost mode is malfunctioning. (Refer to the defect diagnosis function, 8-1-14.)
4. Defrosting won't function if its sensor is defective (wires are cut or short circuited)
