Your freezer temperature could be too high, the water inlet valve may not be functioning correctly, your home water pressure may be low, the refrigerator's water filter may be clogged, or the ice maker may need to be replaced.
Check the water fill tubes
If your ice maker isn't making ice or if the ice cubes are small or misshapen, the water fill tubes may be the problem. Check the fill cup and the tube at the back of the ice maker. If they are covered in ice, look for a blockage.
Unplug the machine and wait 10 seconds. Plug the machine back in and press the ON button. You should see a blue light appear, letting you know that the machine has been reset.
What causes an ice maker to stop working? There are several reasons your ice maker may suddenly stop working, including a blocked water dispenser, issues with your water supply line or a clogged water filter.
To begin the ice-making process, a timer triggers the water valve, which fills the ice mold with water.
If your ice maker isn't producing ice at all or is producing crescents or cubes that are smaller than usual, it's typically indicative of a clog somewhere along the supply line. Cause: A common cause for a clog is frozen water in the line. Fix: To repair a frozen line, slide the refrigerator and unplug it.
Check for ice that's lodged in the dispenser by bending over and carefully looking up into the chute. Solution: If you see a handful of loose cubes, jiggle them free to release them. If ice in the chute seems lodged or stuck, it's best to place a catch under the dispenser and give the ice time to melt on its own.
The ice maker or dispenser could be jammed or broken, a dirty water filter or kinked water line could be blocking water flow or the water inlet valve could be clogged or faulty.
Remove the ice maker from the freezer. Unclog the water pipe with a hair dryer, and remove all the frozen bits from your ice maker by running hot water over it. Dry your ice maker with a rag. Reinstall and wait a few days to see if it happens again.
Be patient because it will take another 3-4 hours before your ice maker is full of ice again. If your ice maker still does not work after following these instructions, then it may have a mechanical problem. This will most likely require a new ice maker to be installed.
If you don't hear a chime and there is no movement from the ice maker, unplug the fridge or turn it off at the circuit breaker for 2 minutes. Then, power it back up and try again.
Fill a bowl or container with warm water and pour it over the ice maker components, paying particular attention to the area where the ice is jammed. The warm water will help melt the ice blockage and free up the mechanism.
Your freezer temperature could be too high, the water inlet valve may not be functioning correctly, your home water pressure may be low, the refrigerator's water filter may be clogged, or the ice maker may need to be replaced.
As time passes, strange things may happen to the refrigerator's icemaking capability. The cubes may be small or there may be a solid chunk of ice instead of individual cubes. It's also possible that the icemaker will stop working. These are all signs of a malfunctioning water valve.
An ice maker freeze up happens when too much water is spread in and around your ice maker and freezes, resulting in damage to vital components. Luckily, there are warning signs and ways to identify when an ice maker freezes up.
Replace the ice maker water inlet valve
The water inlet valve opens to fill the water reservoir when the ice maker first starts and to replace water the freezes on the evaporator plate. If the valve doesn't open or gets clogged with debris, replace the water inlet valve.
First, the icemaker itself is what cycles and sends power to the valve once it cycles in order to fill the tray up with water. I see you replaced the valve already so disconnect the water line going to the icemaker from the valve and blow through it to make sure the water line isn't frozen up above the icemaker.
This usually is due to the water filter being clogged or a restricted water supply. It is recommended to change the water filter first but if the condition still occurs then you want to check for a saddle valve, a water valve not turned on all the way or a kinked water supply line.
To determine if the auger motor is defective, pull out the ice bucket and turn the bucket auger by hand. If the auger turns freely, use a multimeter to test the auger motor for continuity.
Ice Maker Gets Stuck
Remove the ice storage bin from the freezer and break clumped up ice with your hands. Dump any clumps you can't break up into the sink. Since inactivity causes ice clumps to form, the easiest long-term fix is to use the ice maker more frequently.
If you're not noticing results, try leaving the water bottle in the freezer a bit longer, or swap out for one of the extra water bottles that has remained in the freezer. What do you notice about the water as you pour over the ice cube? What do you notice about the original ice cube?
