Icemaker is not making ice cubes. fridge is 3 months old.

There is a heater that comes on to loosen the cubes before they are ejected. If the heater fails and the ejector tries to move, it can cause the gears to strip.

Check the evaporator system, that release the cubes, when that does not work the cubes stay stuck inside.

Threre is one reset button under the ice dispencing unit press it for three second and it will come to your previous setting.

i have same fridge with same prob makes 6 cubes of ice in a day with a lot of noise like you discribed also i have water collecting under crisper drawer of fridge i have to clean out water once a month or so still trying to figure out how to take ice maker out to fix

as long as the fridge is working properly the only thing that it could be would be the icemaker...the fridge should still be under factory warranty if it's 6 months old so they should cover it

Pour about 2/3 cup of water into icemaker ( if there is no cubes in there now ) . If the icemaker dumps the cubes when frozen , replace the water valve . If it doesn't dump , replace the icemaker . Also make sure the coils at the bottom of refrig in front , are clean of dust , lint , pet hair , etc . Also check the plastic hose inside the freezer , to the icemaker , to make sure it is not frozen . If it is , replace the water valve , due to slow drip leak .

I had a Whirlpool Model GD5SHAXNS in which the icemaker quit working about the same time (3 years old). I had water out the dispenser, I found that it was the icemaker itself failed not calling for water to fill it. I replaced it with a icemaker on-line for about $100 and problem fixed. I have been told his is a common problem with the icemaker in this model ref.

Make sure the fill tube going directly into the icemaker is not touching the part that receives the water, if it is touching the water will spray all over and not go into the cavity

your model will have a filter for it. it is located usually on the fridge side torwarss the top back of the fridge. it sounds like you need to replace the filter. it needs to be replaced every 4 monthes or so to keep the water clean. also you may put some water in a cup from the tap/faucet and make sure it is not the water it's self. if it is you may want to think about also having a water filtration system installed in your home.

You may have a problem with the computer control board in the ice maker.  Try this.  Turn off the icemaker for about 2 minutes.  
Turn on the ice maker and press the clear button.  Press and hold this button for 12 seconds to get it to force extract.  This will confirm that the motors will work and push the ice cubes out.  Afterwards, let it run by itself.  If it still doesn't make ice, you will need to replace the icemaker.
