Icemaker Mold Thermostat
If the ice maker is not working the icemaker mold thermostat might be defective. Inside the control module of the ice maker is a thermostat which monitors the temperature of the ice mold (ice tray). Once the mold reaches the proper temperature the ice maker starts a harvest cycle by ejecting the ice cubes and refilling with water. If the mold thermostat is defective the ice maker doesn't advance. The thermostat can be checked for continuity. (See if it is closed). Replace it as needed.The freezer temp should be between 0-5 degrees for optimum performance.
Icemaker Switch
If the refrigerator ice maker is not working, check the icemaker switch. This switch frequently gets turned off by accident. If the switch is turned on but the ice maker still doesn't work, check the switch for continuity with an Ohm meter. Replace as needed.
Ice Level Control Board
If the ice maker is not working the ice level control board might be defective. This refrigerator is equipped with an infrared light beam to detect the level of ice in the ice bucket. As the level of ice reaches the top, the beam is interrupted and the ice maker shuts off. As ice is used up and the level of ice drops below the beam, the ice maker starts up again. If the ice level control board fails, the ice maker will stop making ice.
Door Switch
If the refrigerator ice maker is not working, the door switch might be defective. When the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice maker and dispenser. If the door switch fails the dispenser will not turn on. The switch can be checked for continuity with an Ohm meter. If it doesn’t have continuity it should be replaced.
Icemaker Module
If the ice maker is not working the icemaker module at the front might be defective. The module has a motor that cycles the ice ejector arms around to push the ice cubes out when the ice maker thermostat closes. It also has contacts in it for the mold heater and water inlet valve. The motor or contacts of the module can fail. Usually there are test points in the module that a service person can use to determine if there is a problem with it or one of the related ice maker components.

Thanks. Thermostat seems most likely. I’m leaning toward replacing the whole module since it looks simple (5 screws) and the module runs just about ~$120 on Amazon. Plus my fridge is 5 years old and people say that’s about how long the icemaker lasts anyway. I called a licensed LG repair place and they wanted $500 for a new unit and $200 to install it. Big NOPE.

I have the same problem. Ice maker only dumps manually. I replaced the ice maker. Same problem. Freezer set to -6°F and Fridge set to 35°F. Ice freezes fine. No dump. I get the thermostat issue but, on a new maker and same as old unit? Ice maker is AEO73110210. Fridge is LMXS30776S /01

@hapersson Have you checked the temperature at the ice maker? The display shows what the temperature is set for but that might not be what the temperature is at the I/M. The thermostat is located on the bottom of the tray. It moves when the tray moves to drop the ice. Moving plastic parts will break often. Dirty condenser coils will cause the icemaker to slow down or stop making ice. The coils should be cleaned once a year. More often if you have pets.
If you have below 9*f at the I/M and the coils behind/underneath the unit are clean and the tray fills with water, then you have a problem in the I/M. A gear could be damaged, the tstat isn’t sensing the temp correct or the wiring to I/M is loose or damaged. I’ve had many brand new parts that arrived damaged. Especially ice makers. Parts will come with a warranty. Just because something is new doesn’t mean it won’t break.

@ladytech Thank you for the reply and suggestions. My compressor and coils are good. Just had the bad linear compressor replaced by LG. I put a digital remote probe in the ice maker compartment in front of the probe. The temp has stabilized at 26°F. I removed the ice maker pack and added insulation behind the temp probe and reinstalled the package. Now we wait...Thanks!

@hapersson 26*f is too warm. The ice maker won’t advance until its 9*f or below. If it doesn’t go believe 9*f you should call LG while the repairs are still under warranty. It could be a problem in the sealed system foe why the temperature isn’t reaching temperature. You should check the fresh food section temperature all so.
