Ice maker not working. The water line had frozen water in it. I defrosted it--now clear. The arm does go up and down by itself, therefore still working. It did dump the ice that was in it. It won't start new cycle now. Please help Mary Ann Model SRD 2555W

Either the ice maker or water valve is bad. Is there ice in the form?

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.

Did the ice maker work and then stop working?
Your water line going into the ice maker might be frozen. Try defrosting your freezer and see if it clears things up.

try a full unit defrost clean out vents/drains.

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.
Is the freezer cold enough? Should be close to 10 degrees.
Is there water or ice in the ice mold? If not put water in it and see if it dumps the ice after it’s frozen. If there is ice, lift the cut off arm and let it drop to see if it will start.
If it does dump the ice but don’t refill with water.

ice is stuck in it, take it apart an clean it/defrost

You'll need to first defrost/thaw the freezer and the water line in order to get water flowing again. This can take some time, so you might want to shut off the ice maker by lifting the ice maker bin arm, which will stop it from cycling/calling for more ice to be made.

You can try to thaw the line by using a household hair dryer, but unless you have only a small area of the water line frozen, it could take some time. That is why it is best to empty the fridge/freezer and keep the doors open and the unit off to allow for a complete defrosting of the unit. Have towels, sponges and buckets handy to get all the water.

It sounds like it could just be the frozen water line, but until you thaw it out, you can't really determine if that's all it is.

That on/off arm...you should be able to move it and it will likely make a small click when the switch goes on or off. That arm controls the ice making. There is also a float, is it working freely? It has a switch too. Ultimately, the water is controlled by a solenoid valve. It may be defective. Many of these units are removable to test the switches with a multimeter. Turn off the water and remove to test. Some parts are available...some parts are by the unit only.

change filter and defrost water lines if frozen

check and reset the temp in the ice maker freezer coils them self's
