Icemaker not making ice

The error code dH on your LG refrigerator is indicating a water supply problem. This could be caused by a few different issues:

1. Clogged or frozen water line: The water line supplying the icemaker and water dispenser may be clogged or frozen. This can prevent water from flowing to the icemaker and dispenser. Check the water line and make sure that it is not clogged or frozen.
2. Water inlet valve: The water inlet valve that supplies water to the ice maker and dispenser may be faulty or clogged. This can prevent water from flowing to the icemaker and dispenser. You can check the water inlet valve and make sure it is functioning properly or if it is clogged.
3. Water filter: A clogged water filter can prevent water from flowing to the icemaker and dispenser. If your refrigerator has a water filter, make sure that it is not clogged and has been replaced recently.
4. Water pressure: If the water pressure is too low, it can prevent water from flowing to the icemaker and dispenser. Make sure that the water pressure in your refrigerator is adequate.

You should first try to check the water line, water inlet valve, water filter, and water pressure. If none of these solutions work, please contact a professional technician or LG customer service to diagnose and fix the problem.

Since there is water that flows to the water dispenser, the water valve is working. Now, there's a spout that water flows from to the icemaker tray. Look for it. It's located on the back wall inside the freezer and maybe behind the icemaker tray. Check and see if it's frozen. If so, defrost your freezer by turning the temperature gauge to off position. Wait a while until it's defrosted, then turn it back on.
Next, make sure that the metal wire is in down position.

If that doesn't work, your icemaker maybe defective and needs replacement.

Refrigerator - Icemaker Not Dispensing,or Not Making Ice Check that the feeler arm on the icemaker is in the down position and is not blocked. If the icemaker does not have a feeler arm make sure the icemaker paddle is not blocked under the icemaker. For more information on the causes of new icemakers not making ice. For more information on normal ice production. Side by Side models: The filter may be loaded with sediment that can cause low water pressure. The water pressure must be between 40 and 120 psi. Pressures below 40 psi may cause a malfunction of the icemaker (i.e. producing hollow cubes or no ice production). Test the water pressure: Dispense water from the dispenser into a large measuring cup for 20 seconds. If the measuring cup contains less than 13.5 ounces (400 metric centimeters), the water flow is inadequate. If the amount of water is less than 13.5 ounces then the refrigerator fails the test, remove the filter and test the refrigerator again with the by-pass plug in place. If the refrigerator dispenses the proper amount of water with the by-pass plug in place, then the filter should be replaced. If you no longer have the by-pass plug and it has been over three months since the filter has been replaced, you should replace the filter. If the refrigerator fails the test again and you know you have the proper water pressure in your home, you should call service to check the refrigerator. If the amount of water collected is over 13.5 ounces then the refrigerator passes the test and the dispenser is working correctly. Ice not Dispensing Due To Clumping Ice: Your dispenser may not be dispensing due to clumping ice cubes. The ice cubes in your icemaker may be clumping for a couple of reasons: Low food load: The defrost cycle radiates heat into the freezer. The ice in the freezer will naturally absorb the heat. This will cause the ice to melt slightly during defrost, then eventually freeze together in clumps. Increasing the food load in the freezer will buffer the warmth from the defrost cycle and keeps the ice from melting. Lack of use: When the ice bin is full, the pressure from the weight of the cubes can cause the bottom cubes to fuse and clump. To prevent this from happening, discard the clumped ice and check the bin periodically to ensure the ice is not building up. If you do not use a large amount of ice, move the feeler arm on the icemaker to the up position to turn off the icemaker and stop ice production. For more information on the causes of clumping cubes. If the ice bucket is not seated correctly, ice will not dispense properly. Make sure the ice bucket is in the correct position. Refer to Use & Care manual.

water maybe frozen somewhere in the system. may need to disconnect water connections at various points and retry to narrow down where freeze up is at.

Hollow cubes are caused by not having enough water in the ice mold. Fill it up manually by pouring water in it and see how the cubes turn out.
look for an adjustment behind the plastic endcover with a +/- on it. - is less water. + is more water.


Try swapping the wires on the dual water inlet valve. Then try the water dispenser. The water should go to the ice maker. This will tell you weather or not the ice maker valve is working and if the line is clear.

There is a screen filter before the water inlet valve in the water line. It can get partially stopped up with sediment blocking water flow.

check to see if the hose going into icemaker is frozen. unclog it

Also, check for a frozen fill line too the ice maker. It's the black rubber tube. Try to squeeze it and see if it's blocked with ice.

Check the water valve at the back of the fridge if present.

Even if you used blowdryer, ensure that linse are not frozen by performing a complete defrost.

Disconnect water lines from icemaker, and blow with compressor if the above did not work.

there is only 2 things that would cause this. either the icemaker is bad and not calling for water or the fill valve that allows the water to come into the icemaker is bad. how old is the fridge ? also check the ice maker and make sure it has not accidently been cut off inside. if this is the old type theres a bar that raises and lowers. make sure the bar is down. in the up position this would turn your icemaker off

Check supply tube to see if frozen or blocked using Q-tip or feel to see if frozen. if Frozen, hold up clear glass with heated water placing tube in hot water. Hold till ice in tube melts. Clear glass will allow you see ice slip out.
