If ice is being made , there is no issue with the filter or filter assembly but we will check it out anywqy
With these fridges, it's easier to track down the problem by starting at the valve.
1) turn water off
2) disconnect water line feeding into the valve, it is probably coming from the water filter assembly. As stated earlier, if ice i being made, you shouldn't have a problem with the filter assembly but we are doing this sequentially. Once the line is detached, turn spigot on to see if water comes out of the line. If it does, it confirms the filter and head assembly is good. Reattach water line to valve. Disconnect the larger line connected to the valve. It is a John Guest fitting. Make sure water is on then press dispenser, If water comes out, then you have a frozen line somewhere. If not, you either have a bad valve or an electrical problem.
If water does not come out there are several ways to determine if the problem is electical or the valve itself.
Remove the electrical connection on the water dispenser side of the valve (blue colored chamber). Use a meter to determine if 120vac is found when the dispenser is activated. If you get 120vac, replace valve. If not, check wiring at door. You can also introduce 120v to the valve using a lamp cord, etc and connect it to the valve. The third method is to switch the red and blue electrical connectors but they are different sizes on this particular valve.
