There is water going to the door, but none to the ice maker. it rotates through its normal cycle, but no water goes to it. we took the lines apart and there is no frozen clog or other clogs. what else can this be? we also let it run without the filter and still nothing.
Re: no water supply to ice maker-not frozen in line
The most likely cause is the water solenoid behind the fridge. Take an ohm meter and test across the two terminals and it should NOT ohm out (beep). If it does not ohm out I would replace the P.C. Board kit, emitter & receiver icemaker control.

When the bucket is full the arm is up the maker is off.
If the ice maker has a on/off button in off the ice maker is off
If the ice maker internal heater fails the cubes will not release and the white plastic ejector arms will be rotated CCW and pressing against the ice in the tray, Normal position for ejector arms is vertical.
If water solenoid has failed or water supply not available the ice maker will cycle. The ice tray will be empty,(hard to see if ice tray is empty). Check and replace water fill solenoid.
If ice in tray and ejector arms vertical several possibilities.
Freezer not cold enough to trip thermostat in ice maker to initiate release cycle.
Check freezer temperature <10 Fahrenheit thermostat in ice maker failure
The best way to check the operation is to manually lock the arm up into the off retention position. Wait a minimum of one hour. Open door and release arm down. Observe the operation of the ice maker. Is after a minute or so the ejector arm does not rotate then it is likely the ice maker has failed internally. If the ejector turns and no ice than you can assume either the water supply is off external from the refrigerator or more likely the water solenoid located behind the bottom back cover has failed. It is also possible that the hose that connects the solenoid to the ice maker has frozen right where it enters the freezer just above the ice maker. You should see ice built up at the entrance where the water fills the tray if this has occurred.
Check if the unit has a cold water dispenser that it will fill a cup. If so than problem is with Ice Maker. If not than problem is with water supply to unit.
If water to machine works make sure that the arm on the ice maker is in the down position. If it is up it will disable the ice making unit. Cycle the am a few times to insure that the switch connected to the arm has not gotten stuck in the off position.
On some ice makers there is a separate switch to disable the Ice maker usually right on the ice-maker not easily missed.
It is possible that the water feed tube into the Ice Maker has become frozen where it enters into the back of the freezer at the top. You can look through to see where the water fills into the cube tray. If ice is present it would be an indication that the feed tube has become frozen If suspected the safest way to fix would be to turn off the unit and allow for a manual defrost.
Next check the operation of the ice maker. Locate the arm in the up position prohibiting the ice maker from cycling. Wait three hours or more. Open freezer door and return the arm into the down position. After a few minutes you should observe the ice fingers rotating to release the cubes into the tray. If the fingers do not rotate I would suspect the ice maker or the connecting electrical circuit. Remember after dropping the arm the Ice Maker has to warm up to melt the ice cubes from the tray before the fingers are told to rotate,
If the fingers rotate then I would expect that the water supply solenoid has failed inside of the unit near to the location the the water supply is made. Replacing this part needs to be done by a qualified experienced technician.
if Ice maker cycles and you get no water into it you have a clogged/frozen fill tube. If a broken line the water would go on your floor every 15 min. None of those indicates your refrig valve is bad. Dual solenoid water side works Ice doesn't.
Check the water line that goes from the water fill valve to the ice maker to see if it's frozen shut.
You can remove the ice maker water line from the water fill valve and see if you can blow air through it. If you can't blow through it then its frozen shut.
Sometimes they freeze shut if the water inlet valve was seeping a little water past it when it was off.
If that is the case you have already replaced it so after thawing the water line out you should be good to go.
if the ice maker cycles but is not getting water check the water supply valve that supplies the water to the machine it split and sends water to the door and the ice maker that side of the valve that goes to the ice maker could be bad you can test it with a 120 volt line cord plugged in the wall plug to that side of the water valve if it works with the hose disconnected it may be a blockage or frozen line to the ice maker
the water that is frozen in the fill tube could have come from the old water valve that you replaced ,you got to get the ice out, the easiest way ,though not the fastest ,is to unplug fridge for 24 hrs . and leave the doors open to let it defrost, the plug back up and hopefully in 5 or 6 hrs you'll have ice
