5) Test Function

This function is useful when there is a need for forced operation for testing purposes, A/S, cleaning etc. This function is executed when the test S/W attached to the automatic ice maker itself is pressed for more than 1.5 seconds.

5-1) The test function by pressing test button cannot be engaged during ice extraction, horizontality noise or water supply operation but can operate when in the horizontal condition. Also, the test function cannot operate when ice is full. The operation is only feasible when full ice has been relieved..

5-2) If the test button is pressed for more than 1. 5 seconds in horizontal status, the ice extraction is operated directly regardless of the ice making condition of the ice maker container. Beware that water pours out if test function operates with unfrozen water. 1 cycle of water supply is executed at the horizontal noise operation after the ice transfer operation. Therefore it is feasible to check ice extraction operation, horizontality operation and water supply problems by using the test button. When the test function is normally executed, the buzzer sounds “ding dong” and the water supply function is executed. If buzzer does not sound "ding-dong", it signifies abnormality so check and repair is needed.

5-3) If the water supply has finished, it then goes through a normal cycle of ice making

water supply again.

 

6) ICE OFF Function

Ice making can be stopped by pressing the ice selection button to select ICE OFF when either ice is not wanted or its use is not needed.

6-1) ICE OFF is selected if the ice selection button is pressed on the DISPLAY and ICE OFF is canceled if the button is pressed again.

6-2) When the electric power turns on, the refrigerator operates automatically in the ice making mode where fragment ice is automatically selected and the lamp is lit.

6-3) If you want to, ICE OFF is selected by using the ice selection button, then the ice maker does not operate and it maintains the stop condition.
