MY LG refrigerator dispenses water into the ice tray, freezes the ice and then tilts the tray but does not complete the process of dumping the ice. Eventually it gives me an Error 15 and when I do a diagnostics test on it shows an Error IS. I have changed out the ice maker. I have changed the main board on the fridge I have changed the board that is located on the top of the left fridge door ( sub PCB board ) I did an ohm test on the connector 11 & 12 of the ice sensor cable and those are showing normal. When I do the test to check if the refrigerator thinks the ice tray is full it does show FULL, even though there is no ice in it. Any thoughts or suggestions would be great…
Hi @kentdes , According to the service manual(p.109) if you do the ice maker diagnosis test (sect13.3.2) then FULL means that the ice detecting sensor is faulty This is from the manual: If ETY is shown on the display after the procedure above, Ice-detecting sensor is normal. If FULL is shown on the display after the procedure above, Ice-detecting sensor is abnormal. ETY = empty Since you have tested that the sensor is OK these are the other possibilities according to the manual: Cap duct bad sealing Defective thermal sensor in the icemaker compartment Not cold icemaker compartment area (sealed system)
