I have an LG refrigerator with a bottom freezer. We recently replaced the water filter as it was more than 6 months old. Once the water filter was replaced we noticed the ice maker did not make ice. I replaced the ice maker, water valve, and a water line and still no ice from the ice maker. I am beginning to think it is a wiring problem or a control board issue.
Quick Answer: Check your water filter. Make sure the water filter is IN completely. If the water filter in your refrigerator is not installed properly water cannot flow through it. Remove the water filter and inspect it. Slide the water filter back in and be sure you PUSH AND TWIST to lock it in. LG Refrigerator Manuals Here.
The water filter on newer refrigerators need to be “Twist Locked” into place. If the water filter is not installed correctly the water will not flow and therefore no ice or water will come from the dispenser.
This is a very common issue with newer refrigerators. Many times when the water filter is changed, the ice maker stops working. This is often misdiagnosed and people think the ice maker is bad. We have seen people ordering ice makers, send them back, and reorder a new one, only to find out the ice maker still does not make ice. The ice maker will never work if the water filter is not installed correctly.
LG Refrigerator Water Filters – How Often To Replace Filter?
If you have recently changed your refrigerator water filter and the water dispenser/ice dispenser stops working, the filter was not installed properly. When this happens follow the steps below…
1. Turn off the water to the refrigerator if needed.
(most refrigerators have a water shut off behind the water filter and manually shutting off the water is not needed)
2. Remove the water filter and other pieces of plastic.
3. Check the water filter and filter housing for anything that may prevent it from connecting.
4. Replace the water filter by pushing in and twisting it until it locks into place.
5. Turn the water back on if you turned it off.
6. Check to see if water or ice dispense.
If the ice and water dispense, the water filter was not installed properly.
If you continue to have issues with the ice maker or water dispenser you will need to check the following…
Reasons why your ice maker stopped working
1. Water filter installed incorrectly – MOST LIKELY
2. Water inlet valve is faulty
3. Water line is bent, kinked or frozen
4. Ice maker/dispenser motor faulty
5. Wiring issue
6. Board issue
REFRIGERATOR WATER INLET VALVE
Check water inlet valve at back of fridge to be sure it is opening to let water in.
Use a meter and be sure it is working.
Replace it if you find an issue.
HOW TO TEST WATER INLET VALVE
REFRIGERATOR WATER LINES
Check water lines to be sure they are not bent or kinked.
Bent water lines will let some water though but not enough to work correctly.
Replace any water lines that you find damaged or extremely kinked.
REFRIGERATOR ICE MAKER
Check that the ice maker is working properly.
Be sure the ice maker cycles and the ice tray is turning.
Use the button on bottom of ice maker to test/reset.
Make sure water is getting to the ice maker.
Use a multimeter to be sure the ice maker gets power.
If ice maker tray does not turn it may be jammed.
Unjam the ice maker by removing all ice and resetting it.
HOW TO REMOVE ICE MAKER
REFRIGERATOR WIRING HARNESSES
Check and secure all wiring to ice maker, dispenser, and boards.
If the wiring harnesses is not connected properly a component may not work.
If you find any lose wire harnesses, reconnect.
If you find any damaged wiring, replace or repair the wiring.

LG lmxc23746s/01 Ice Maker not filling with water. I have:
1. replaced water filter
2. reset ice maker
3. replaced ice maker
4. replaced main water valve
5. replaced water/ice valves
6. replaced sub PCB
7. replaced fan motor that serves ice maker compartment
Now, the ice type button is no longer working
I have inspected wire connections, including connectors at top of door. Only part that I have not replaced is the main PCB control board. Used LG phone app and it states nothing is wrong. Any suggestions???
LG LMXC23746 icemaker will not fill with water. I have pressurized the RO tank and the water dispenser works. I have activated the reset button and the tray dutifully rotates and twists. But with the icemaker turned to ON, the ice tray will not fill with water.
This is a fix we discovered for our LG French Door Refrigerator with the ice dispenser in the bottom freezer area. There is no reset button on this model: LFRD25850SW. The ice maker quit running and we realized the ice was frozen solid in the ice maker; we could not feel any of the blades, etc.. We emptied the bin, and poured hot water into the filling area until all of the ice floated up and into pieces. The ejector blades were positioned in the down position near the front of the ice maker and easy to move so we let it fill, dumped the extra water into the bin and it works!
This will help owners who have models without ice maker door dispensing as a possible first step rather than replacing ice maker parts or buying a new refrigerator.
I have a newly installed LG LFXS28968S refrigerator. The water dispenser is working but the icemaker is not. The ice tray has not filled with water after eight hours since installation. I checked online advice and it said to push and hold the test/fill button. I have taken out the storage unit and looked under the icemaker and don’t see any such test/fill. I have turned the on/off switch on and off several times. The ice tray rotates slightly but water does not come into the tray. I’d appreciate any suggestions you have. Thanks.
