FLEX TRAY Ice MakersWhen the initial power is applied, the ice tray will stand by for 2 hours.After the 2-hour standby time, the Ice Maker Sensor will check thetemperature , when it is lower than 1.5℉ for more than 5 minutes, itwill do a harvest, with or without ice in the tray, then fill with water. 58minutes after water is supplied to the Ice Tray, the Ice Maker Sensortemperature will be checked. When the Ice Maker Sensor maintainslower than 1.5℉ for 5 minutes, it completes the harvest (if the ice binis not sensed as full). Thermistor senses temperature to determinewater fill on newer unitsFilling the trayAfter the water fill is completed, the ice maker sensor will evaluate thewater volume one and a half minutes later. When it detects no or lowwater level, it will add more water. First supply time will be 1.5 sec,next one will be 1 sec and the last will be 2 sec.Guide – Bin FullIce Maker Test ButtonIce Maker ThermistorNO Error LED Display1 ICE MAKER SENSOR Right-1 LED ONShattered Ice – Flex TrayWhen all ice shatters, it's because of a badtray or ice cube temp that is too cold (lowerthan -5 degrees). In some areas, there arewater issues that can also cause shatteredcubes. The temp in the freezer should nothave any effect on this issue, as long as it’sbelow 1.5 degrees F, as a properly installedsensor will not read the freezer temp, only thewater/ice temp.Check the Ice tray for defects in the plastic.Ice that is too cold will shatter duringharvest. This can be from the (1) sensor notreading the correct temp (2) or the sensor notmounted correctly (3). By programming theicemaker offset value to a lower number (4),the board not understanding the reading.To check the sensor, you must check the traytemp (not air temp) and compare it to the sensorreading. The sensor should read 3.7 voltsat the main board connector when the cubetemperature is 1 degree. After the fill, the sensorwill read water temp 1.5 to 2.2 volts.To clear offsets, put unit into Diagnosticsmode.Please note, some shattering is normal fora flex tray icemaker.2 R-DEFROST SENSOR Right-3 LED ON3 R-SENSOR Right-4 LED ONRefrigerant ChargeR134a 7.41 oz.4 R-FAN ERROR Right-5 LED ON5 R-DEFROST ERROR Right 6LED ONSealed System6ICE MAKER FUNCTIONERRORRight-7 LED ON7 EXIT-SENSOR Left- 1 LED ON8 FREEZER SENSOR Left- 2 LED ON9 F-DEFROST SENSOR Left- 3 LED ON10 FREEZER FAN ERROR Left-4 LED ON11 C-FAN ERROR Left-5 LED ONCompressor → Condenser →Side Cluster →Hot Pipe→ Dryer → R Capillary → R Evaporator→ F Evaporator → Suction Pipe →Compressor12 F-DEFROST ERROR Left-7 LED ON# tsRS263TD RevB 03/30/2011 4
