TURN OFF FREEZER HALF TO DEFROST WATER LINE THAT FEED ICE MAKER

These symptoms occur when the fresh water line that supplies your ice maker and water dispenser is frozen.
You will have to trace the water line from the ice maker to the back of the fridge and defrost that line. After defrosting all will work as normal but the first few batches of ice should be discarded. It is also advised to replace the water filter due to impurities from the melted water.

Try firs unplugging power for 510 minutes, see if it reset.

1, ice maker may need to be replace, 2 water line may be frozen , if so turn off the freezer to defrost it for few hours, 3. when was the last time to replace the water filter? make sure you replace it when the time expired.

try a full unit defrost clean out vents/drains.

Hi There
I have found this for you,read this and let me know how it goes.
The ice maker is producing ice poorly When an ice maker is producing ice poorly--when it produces just a few cubes or none, or when the cubes are too small--it's usually because of a clogged water line or a defective water inlet valve. First, check the water line attached to the back of the refrigerator for good water flow. To do that, first turn off the water supply valve. Then remove the water line from the back of the refrigerator. Next, place the water line into a bucket and momentarily turn the water valve back on to test the flow. If the flow is poor, you need to repair, clean, or replace the tubing or the shut-off valve that supplies the water. If the flow is good, you may have to replace the water inlet valve.
Thank you for writing to fix ya.
Best Regards Richard

Sometimes icemakers get all frozen up, such that the motor cannot turn to eject the ice. Also, in some cases the water supply line freezes up, although that does not sound like your problem.

Try leaving the freezer open to defrost it manually and see if it starts working by itself. Also, the icemaker motors can and do fail. In some cases you smell an acrid burning smell when the motor fails.

The ice maker has a problem The ice maker is a separate appliance within the freezer section. Please see the How things Work section of our website to learn about the normal functioning of ice makers. Some common problems with ice makers are:

The ice maker has completely stopped producing ice
The ice maker is producing ice poorly
The ice maker has completely stopped producing ice Check to see whether the ice maker has been turned off. Here's how to check. Look for a wire along the right side of the ice maker that looks a bit like a coat hanger. If this wire is in the raised position, the ice maker is turned off. On some units you simply lower the wire to the down position to turn the ice maker on. On others, you lower a small red plastic lever to lower the wire. If the wire is in the proper position check the freezer temperature, it should be between 0-8 degrees Fahranheit. If it is warmer than 10-12 degrees, the ice maker may not produce any ice. Check your door seals and thermostat, repair/replace as necessary.

There's an ice- or water-dispensing problem The ice and water-dispensing system of your refrigerator is quite complex. Many components work together to provide the ice and water. Aside from a simple problem of a leaky water tube or a jammed ice chute, most other components are not user serviceable. We suggest that you contact a qualified appliance repair technician for such repairs.
