The water dispenser is working fine, but there is not water going to the ice maker. The ice maker is turned on. I have removed the filter and put in the bypass plug. Any suggestions?

Can you provide a make & model # for the unit?

If your ice maker is working your filter is fine. You need to check the solenoid valve that feeds the water dispenser. You should have 2 of them on the water line. One that feeds ice maker and one that feeds the water dispenser. That is most likely your problem

You need to replace the ice maker

You have a bad water filter housing. Be sure to turn of the water to the refrigerator before replacing this part. Replace the filter at the same time.

You probably have an obstruction in filter compartment. you should remove filter and inspect o rings etc. or anything that could have clogged it up. The only other thing that could be the cause is a bad water valve. Side by sides have a double water valve. one for water ,one for ice maker. You can check this by having someone flip ice maker arm down so it calls for water and feel water valve as it runs and possibly hear it too. Hope this helps.

The same thing happened to me. If you pull the refrigerator out and remove the large silver panel, you will see the water lines on the left. The line going to the ice maker was fine, but the line going to the water dispenser was split. You may have the same issue.

Check the following:

Is the freezer door closed completely?

Is the ice storage bin installed correctly?

Is there ice in the storage bin?

Has the ice frozen in the storage bin?

Is ice stuck in the delivery chute?

Has the wrong ice been added to the storage bin? Use only
cubes produced by the current ice maker.

Has the ice melted around the auger (metal spiral) in the
ice bucket? Dump the ice cubes and clean the ice storage
bin.

Is the ice dispenser stalling while dispensing “crushed”
ice? Change the ice button from “crushed” to “cubed.” If
cubed ice dispenses correctly, depress the button for
“crushed” ice and begin dispensing again.

Has the dispenser arm been held in too long? Ice will stop
dispensing when the arm is held in too long. Wait 3 minutes
for dispenser motor to reset before using again.

The ON/OFF switch is located on the top right side of the freezer
compartment.
To turn the ice maker on, slide the control to the ON (left) position.
To manually turn the ice maker off, slide the control to the OFF
(right) position.
NOTE: Your ice maker has an automatic shutoff. The ice maker
sensors will automatically stop ice production, but the control will
remain in the ON (left) position

REMEMBER:

Allow 24 hours to produce the first batch of ice. Discard the
first three batches of ice produced.

The quality of your ice will be only as good as the quality of the
water supplied to your ice maker. Avoid connecting the ice
maker to a softened water supply. Water softener chemicals
(such as salt) can damage parts of the ice maker and lead to
poor quality ice. If a softened water supply cannot be avoided,
make sure the water softener is operating properly and is well
maintained

The Dispenser Lock (on some models)
Your dispenser can be turned off for easy cleaning or to prevent
unintentional dispensing by small children and pets.
NOTE: The lock feature does not shut off power to the product, to
the ice maker, or to the dispenser light. It simply deactivates the
dispenser levers. The ice and water dispensers will not work.
Style 1: Press the LOCK BUTTON to lock the dispenser. Press the
UNLOCK button to unlock the dispenser.
Style 2: Press and hold the LOCK OUT button to lock the
dispenser. Press and hold the LOCK OUT button a second time to
unlock the dispenser.

check the water valve on the back of the ref. it sends water to the ice maker and water in the door one can work and the other one not

Take the icemaker out and let it sit in the sink for around 12 hours. Then put it back in. This has worked for me when I have the same problem. I think that the water line is freezing up. I have to do this every month or two.

at the very least replace that water filter.clogged water filter will reduce water pressure to the line.
