OPERATING INSTRUCTIONS & INSTALLATION

4-2) Step 2 : operation is to overturn tray in order to separate the ice in the ice tray where tray is overturned by direction rotation of ice extraction motor.

-In case the storage container is full ice: if the ice extraction S/W is ON again before 3.6 seconds elapse from the time the extraction S/W condition changed to “on off” has occurred after starting rotation of the ice extraction motor, then this means that the storage tray is full of ice so that direction rotation of the motor is interrupted so as to start reverse direcion rotation (horizontal movement) after waiting a second. Step 6 is executed.

- In case the storage is not full ice: if the ice extraction S/W is not ON again after 3.6 seconds from the time when the ice extraction S/W condition changed to “on off” has occurred after starting rotation of the ice extraction motor, then this is judged to mean that it is not full of ice, in which case normal ice extraction movement is performed and step 3 is executed.

4-3) Step 3 : if the ice extraction S/W is not ON again after 3.6 seconds from the time when the ice extraction S/W condition changed to on “on off” has occurred after starting rotation of the ice extraction motor, then this is judged to mean that it is for normal ice extraction operation. If F compartment door is opened during ice extraction operation thereafter, operation stops for a while and restarts after Door Close.

4-4) Step 4 : motor rotation stops if the ice extraction S/W turns on after 3.6 seconds have elapsed from the start of the rotation. This point is the maximum torsion point and waits a second under this condition.

4-5) Step 5 : It is a step that ice extraction restores horizontally accomplished by reverse rotation of ice extraction motor. So after step 4, the ice extraction motor turns in the reverse direction when the ice extraction S/W always senses the full ice lever signal regardless of the ice existence of the ice storage container so as to be called the "Return Pulse".

4-6) Step 6 : if the ice extraction S/W turns ON after the "Return Pulse, the reverse rotation of the ice extraction horizontally motor stops and the ice extraction is judged to be in the horizontal position. If now it has been restored horizontally after sensing full ice, water is not supplied but ice extraction is retried consecutively in 1 hour intervals until full ice cancellation. So thereafter, water is supplied if normal ice extraction has been performed.

4-7) Figure shows operation specification of ice extraction (in case of non full ice / full ice).
