Installation
Ice is clumped together
Power failure
The unit is newly installed
Throw away the ice.
The first ice and water may include particles or odor from the feed water pipe or
feed water box.
This is also necessary if the refrigerator has not been used for a long time.
Never store beverage cans or other foods in ice storage bin for the purpose of rapid
cooling.
Such actions may damage the automatic ice maker.
Never remove the icemaker cover.
Shake the bin occasionally to cause the ice to settle.
Ice may pile up just around the icemaker causing the icemaker to think that the ice
storage bin is full.
If discolored ice is dispensed, contact an Authorized Service Center immediately.
Do not use the ice or water until the problem is corrected.
When ice is clumped together, take the ice clumps out of the ice storage bin,
break them into small pieces, and then place them into the ice storage bin
again.
When the icemaker produces too small or clumped ice, the amount of water
supplied to the ice maker must be adjusted. Contact the service center.
If ice is not used frequently, it may clump together.
Water may drop into the freezer compartment. Take the ice storage bin out and
discard all the ice. Dry the bin and replace it.
It takes about 12 hours for a newly installed refrigerator to make ice.
