Brian for Model Number LGHB2869LF3 My ice maker won't make ice. I replaced the ice maker with 243297606. The ice maker diagnostics all pass. As far as I can tell, the issue is that the fresh food ice maker is not getting cold enough. The diagnostics show it at anywhere between 20 degrees and 47 degrees, depending when I check it. I used a hair dryer to defrost the coils and fan behind the ice maker, fan spins and all seems to work as it should. In fact, if I use the diagnostic screen to put water in the ice mold, it quickly freezes. When I use the diagnostic screen to dump the tray, it does as it should. I can manually run the whole cycle, but it will not go automatically.
Answer Hello Brian, based on your testing, the ice maker is working correctly as per the test mode but not getting cold enough as measured by the ice maker thermistor to cycle in normal operation, since the ice maker has its own evap coil, this may be a ice maker evap fan problem or a ice maker evap defrost heater problem, if both are testing ok then replace the main control board.
