Our refrigerator was not dispencing water or ice.
Turned of water to refrigerator and unplugged refrigerator. Removed the water line from refrigerator. Removed back panel. Removed mounting screw from the water valve, Unhooked wire harness from valve and removed the water line on back of valve. Reconnected wiring harness to new valve, reconnected water line on back of valve. Replaced the back panel to refrigerator and put the water line back on the new valve. Turned on water valve and checked for leaks. It's now dispensing water and ice.

Water inlet valve was leaking
0) Look on the internet for a DIY/or pro-shop Video
1) Pull the refrigerator away from the wall, unplug the power cable
2) Shut off the water at the wall valve
3) Disconnect the water line at the inlet valve on the refrigerator (lower corner, right side), this is a threaded pipe fitting requiring a small open end wrench
4) Remove the lower rear panel
5) Remove the water inlet and distribution valve assembly, there is one sheet-metal screw holding the assembly to the back edge of the refrigerator.
6) Carefully pull the assembly out of the back of the refrigerator, leave the distribution water lines attached, note the orientation
7) Disconnect the electrical connectors, note the orientation/types
8) Disconnect the water line from the inlet valve, remove the retaining clip, then pull out the line. Note - a small metal star shaped tube fitting may come out with the valve, this is fine and will not be used again.
9) Remove the inlet valve from the assembly (there are two small sheet-metal screws that are very tight, the correct/precise size, good quality Philips head screw driver is necessary or use a small set of vice-grips to grab the head of the screw)
10) Attach the new valve to the valve assembly, connect the electrical connectors, note - at the plastic refrigerator water line that connects to the inlet valve, trim/cut a small section off the end of the water line before connecting it to the valve. This will provide a fresh interface for the connection. Push the line in firmly and then install the retaining clip.
11) Perform a quick functional check before putting everything back together - Attach the water line from the wall, turn on the water, attach the electrical connectors, plug in the refrigerator power cable and test for operation and leaks.
12) Assuming no leaks/operational issues, unplug the refrigerator power cable again, turn off the water at the wall, disconnect the water line at the inlet valve and reinstall the valve assembly and rear panel. Reconnect the water line and plug in the power cable and you should be good to go.!

Replacement water valve.
Easy job. Just don't get the parts from this place. First part was no good and delivered was past deadline after I paid for expedited shipping. Had to get new part delivered which in three days increased in price and then still waited for ten days WITH expedited shipping. Have not been reimbursed for first part that was no good AND my expedited shipping fee. Shop somewhere else.

Replace water valve
I waited for 2 weeks for a professional appliance repairman to fix my water leak. He kept telling me he was trying to get the part. I finally gave up on him and ordered the part online. Only took a few minutes for the repair. Got the part via mail in 3 days.

First we had a problem with the back plate getting stuck - where you press your cup against to dispense water. The water kept flowing until we opened refrigerator door or got the plate unjammed. A few months later the secondary 1-inch sized water dispense button started getting stuck in the on position. Finally we had to turn off water because it wouldn't stop flowing and shooting on to the floor.
For model number LMX25984ST

Hi Tamara, Thank you for your question. If the button is getting stuck I would try replacing it if that what was causing the the water to flow continuously. I hope this helps. Thank you and have a great day!

The replacement water intake valve has only two wire leads whereas the old one has 4 wires. What to do?
For model number Lfx25960
PartSelect logo
Hello Lori, Thank you for your question. The correct water valve with four wires for your model is under part PS3527439, the valve you have will not work with your specific model. We hope this helps!
