13-2 ICE MAKER FUNCTIONS 13-2-1 Icemaking Mode 1. Icemaking Mode begins right after the ice tray fills with water. 2. Icemaker waits until water becomes ice in the ice tray. ※ Ice-detecting sensor checks if the ice bin is full every 2min. 13-2-2 Harvest Mode At least in 110min, since icemaker begun icemaking mode, Icemaker starts to twist the ice tray to drop ices into the Ice bin. (After installation, at least 1day is needed to make ices) ※ If the icemaker never drop ices to the ice bin though water becomes ices in the ice tray, check the real temperature of compartment. (not temperature on display) Icemaker needs below 0°F to drop ices to ice bin. 13-2-3 Fill/Park Position Once the normal harvest mode has been completed, the water solenoid will be activated. 13-3 Trouble Shooting Ice & Water system Issues 13-3-1 Icemaker not making ice or not making enough ice (Environmental Diagnosis) ▶ Icemaker can't make ices itself. Basically, water, temperature and time are needed. - Water : If no Water, then no Ice. - Temperature : The compartment, where the icemaker is located, has to be at least 1°F so that icemaker dumps ices to the bin. - Time : At least 80 minutes must be passed to make one series of ices after water comes into icemaker. ※ Test Mode should not be carried out before checking below. Not making ice Water Is Icemaker's tray filled No with water or Ice? Temperature Yes Is measured temperature below 10°F No in the icemaker compartment Time Yes How long has customer No waited for icemaker to make ices? 1. Is saddle valve turned on? → Check saddle valve. 2. Is the icemaker fill tube frozen? → Check the fill tube heater's electrical resistance. 3. Are water valve housings are connected properly? → Check all the water valve' connection. 4. Water line kinked or damaged? 5. Is water filter too old? 1. Does cold air come out from air vent normally? → Check if Icing fan is working. Check if multi duct is blocked. 2. Are the R & F room cold enough? → Measure the temp. and Check gas leakage at the back. 3. Does icemaker compartment door close tightly? 1. At least 120min. must be passed to make ices after water comes into icemaker. 2. At least 24 hours must be passed to have ice bin full of ices. (not in case of installation) If the issue haven't resolved yet, though you have checked all the items above, go to next step. - 68 -

13-2 ICE MAKER FUNCTIONS
13-2-1 Icemaking Mode
1. Icemaking Mode begins right after the ice tray fills with water.
2. Icemaker waits until water becomes ice in the ice tray.
※
Ice-detecting sensor checks if the ice bin is full every 2min.
13-2-2 Harvest Mode
At least in 110min, since icemaker begun icemaking mode, Icemaker starts to twist the ice tray to drop ices into the Ice bin.
(After installation, at least 1day is needed to make ices)
※
If the icemaker never drop ices to the ice bin though water becomes ices in the ice tray, check the real temperature of
compartment. (not temperature on display)
Icemaker needs below 0°F to drop ices to ice bin.
13-3 Trouble Shooting Ice & Water system Issues
13-3-1 Icemaker not making ice or not making enough ice (Environmental Diagnosis)
▶
Icemaker can’t make ices itself. Basically, water, temperature and time are needed.
- Water : If no Water, then no Ice.
- Temperature : The compartment, where the icemaker is located, has to be at least 1°F so that icemaker dumps ices to
the bin.
- Time : At least 80 minutes must be passed to make one series of ices after water comes into icemaker.
※
Test Mode should not be carried out before checking below.
13-2-3 Fill/Park Position
Once the normal harvest mode has been completed, the water solenoid will be activated.

waited for icemaker to
make ices?
1. Is saddle valve turned on?
→
Check
saddle valve.
2. Is the icemaker fill tube frozen?

’s electrical
resistance.

.
2. Are the R & F room cold enough?
→
Measure the temp.
and Check
gas leakage
at the back.
3. Does icemaker compartment door close tightly?
1. At least 120min. must be passed to make ices after water comes into icemaker.
2. At least 24 hours must be passed to have ice bin full of ices. (not in case of
installation)
