7-2-4 Ice-removing control function
1. Ice-ramoving control means operation to separate lee within ice-making tray ( lee-making container) after ica-making is
completed.
2. Step to check ices stored at the ice bank (container for storing ice) are fully tilled. It is considered as they are fully tilled if
signals of the hall sensor are at the On status ("high_) before 3.6seconds after rotating positively the ice-making motor. In
this case, the ice-making motor remains at the waiting status without performing ice-remeving function.
Perform ice-detecting operation after rotating pceitively the ice-making motor in the cycle of an hour if the full ice status is
detected. Perform water supply control function after completing ice-mmeving function inthe short of ices stored.
Reversely rotating the ice-mmeving motor in the storage of full ices and then let the motor stop at the position of the ice-
making or waiting status.
3. Ice-ramoving control performs ice-removing operation immediately if ices stored at the ice bank (container for storing ice)
are not fully tilled (the hall sensor are at the Off status ("low') within 3.6seconds after rotating positively the lee-making
motor). In this case, it positively rotates (CW) the ice-removing motor and keeps the ice-making tray at the maximum dis-
tortion status and makes ices be separated from the ice-making tray. in this case, ice-detecting lever automatically oper-
ates lifting operation with ice-removing operation.
4. Ice-removing control positively rotates (CW) the ice-removing motor and stops it for a second as it considers as maximum
distortion point (ica-detecting axle = 160 °) if the sensor signal changes from the Off status (=loW') to the On status ("high")
after 3.6 seconds pass.
5. Ice-removing control positively rotates (CW) the ice-removing motor at the cycle of an hour if problems in ice-making
motor or hall sensor are found and performs initial operation or operates initialization of product if normal
6. Ice-removing control stops for a second at the maximum distortion status of the ice-ramoving tray (container for storing
ice).
7. Step that the ice-removing tray stops for a second and then returns to the level. It returns to the level status returns to the
lee-removing tray by reversely rotating the ice-making motor.
8. The cycle of "water supply , ice-making • ice-removing • returning to the level" if becoming the level status.
