Ice maker will not fill with water, help

by Manage My Life Last activity date:
September 30th, 2011

We have a LG refrigerator with freezer on the bottom model LFX25950SB it will dispense water out of the door but will not fill the icemaker, we can pour water in the icemaker and it will freeze and empty the cubes, but will not fill with water. do I need to replace the water valve on the bottom of the refrigerator will the water line connects or is there another valve and solenoid in the door somewhere? we have tried resetting the icemaker but no luck

I'm glad you found the problem. The main valve is # 5221JB1004N and is available at the link listed below. Thank you for using Manage My Life.

Wrong Again! The water lines are connected properly. the problem is the main water valve. It has 2 solenoids, one for the water dispenser and one for the ice maker. The icemaker one is not working.

When the icemaker runs through the cycle, and I put the plug from the icemaker side of the water valve on the solenoid of the dispenser, water flows properly.

Did not need icemaker, first water valve I bought, need main water valve which has 2 solenoids and problem will be solved.

I'm sorry for the confusion. I can see that this is a triple solenoid but the wiring diagram only shows it to be a dual solenoid, which is what is causing the confusion. However, looking at the water valve, when the icemaker is activated, the jumper wires to the main solenoid should also be energized and open both valves. Since it does work ok when the dispenser wires and icemaker wires are reversed, it does indicate the water valve is ok but the water lines may not be connected properly. I suspect the line from the filter to the valve may be connected to the outlet of the dispenser solenoid and the line from the dispenser may be connected to the inlet of the dual valve. I'm attaching a picture of the water line configuration and I hope it helps you. If it still has the same problem, a technician will be needed to check this. It will be a situation that will need to actually be seen, to determine what needs to be done.

There is the problem. I added onto another thread with a different model number. Perhaps that is causing the problem. I have a LRFD25850TT refrigerator and it definitely has 2 solenoids. All of the issues are the same.

Here is a link to pics of what mine looks like.

repairclinic.com/Model-LRFD25850TT-ID-684712-Valve-Or-Float-Assembly-Parts

I apologize as I was sure that when I registered it asked me the model number and I assumed you knew it. If you have new ideas, please let me know as I am deep into this and still no ice. Wife is getting itchy!

Thanks!

I'm sorry, I have checked with several other techs also and we all come up with the same technical information. If you have this extra wire and solenoid, please recheck to verify the model number listed here is correct.

I respectfully disagree with the manual or information you have. The plug that attaches to the solenoid I bought, has a jumper to a second solenoid that activates at the same time. the water passes through the main solenoid, through the filter, through the second solenoid, to the icemaker. At least that is how it appears to me. I will inspect the lines again, but I am relatively sure that they are in the corect places as I was very careful when I replaced the solenoid not to confuse...but will let you know.
Thanks

From the model number listed LRFD25850TT, the icemaker only activates one solenoid. It will be the red and blue wires and this solenoid opens the water line, straight to the icemaker. Another possibility could be if the water tubes got reversed. On this model, the main supply will connect straight to the filter and then comes out to the inlet on the dual valve, in back of the unit. This valve separates the dispenser and icemaker. Check to see if the line from the filter is connected to the outlet of the valve and if the line to the dispenser is connected to the inlet. If these 2 lines got reversed, it would cause the problem your experiencing. I hope this will help you.

It occured to me that not only does the ice maker solenoid have to energize, the main water solenoid must energize as well. Perhaps it is not getting power through the jumpers or somehow that is the problem.

I will test it to make sure it is getting power. The board, although the last item to replace, seems like a long shot.

This is very strange. From the information listed, the valve is getting the proper voltage and should be working. Since it does open, when you reverse the dispenser wire leads, it does indicate the valve is ok. From what has been replaced already, it only leaves the board. At this point, without actually being there to see what is happening, I would agree about replacing the board. However, this just seems strange that apparently the voltage is there, with the wires still connected to the valve and the valve is not opening but it will, if the dispenser lead is connected and activated. I would recommend having a technician check this before replacing the board. You can call 1-800-469-4663 to schedule a tech to come out. Thank you for using Manage My Life.

Tested the voltage while it was connected to the solenoid and there was no drop in voltage while the solenoid was engaged. The solenoid turned on for approximately 6 seconds and the voltage was above 115 the entire time. I do not understand that as I would have suspected that the voltgage would drop below 100 indicating it needed more power to open.

With that said, still no water and has water when jumpered to the water dispenser. I do not see a yellow wire, unless it is located behind the icemaker and in the plug on the back of the freezer wall.

it would be strange to have a cracked wire, which leads me to the main board. Before this is all over I will have replaced the entire system...for some ice!

Another check you can make will be to disconnect the power to the unit and then disconnect the icemaker harness connection. Now place a jumper between the yellow and red wires in the harness. Reconnect the power and water should flow to the icemaker. If no water flows, it will indicate that either the main board # 6871JB1280P, which is located behind the unit, has failed or there is a broken wire in the cabinet. The most likely problem will be a failed main board. A technician would be required to check and verify if it has a broken wire. I hope this will help you.

I have already replaced the icemaker. So now I have a new icemaker, new solenoid, and same problem...no water. I can check voltage while cycling...I know how to do that but the problem is I am not getting the amps. Where exactly does the solenoid get its power? Does it come from the board and if so, which board?

Any more tests?

Thanks

Since water did flow to the icemaker when you switched the wires from the dispenser, it does indicate the water line is clear. Since the valve has been replaced, I recommend cycling the icemaker manually and checking the voltage at the water valve when the icemaker calls for water toward the end of the cycle. I'm attaching a picture with instructions to cycle the icemaker. Be very careful making this check and make sure the wires are still connected to the valve when making this check. There will be a voltage drop to the valve but it should still get approx. 100 volts to it. If this voltage is not there, the problem could be with the icemaker or the main board. This can be difficult making these voltage checks and I would recommend having a technician make these checks. Another check you can try will be to lower the icemaker and place a jumper between the black and red wires. Be sure to disconnect the power first. With the jumper in place, reconnect the power and if water now flows to the icemaker, the icemaker will need to be replaced. If no water flows, since the water valve has been replaced, it would lead to a defective board but to determine for sure, the board will need to be checked. I would recommend having a technician make this check. If you would like more assistance, I will be glad to assist you further.

Water valve came today and problem not solved. Water still not entering tray. I do get 120v when I run the icemaker through the cycle and I hear the solenoid make noise like it is opening, but does not pass water.

I switched leads to the water dispenser and then water flows to the ice maker as it should. I do not know why 120v through the icemaker is different than 120v through the water dispenser, but I tried it over and over and i get the same result.

What now?

Thanks!

That's what I am thinking. I will switch water lines and confirm, but I bet that is it. Thank you for your help. Sears has the best price on the item as well!

Based on this additional information, the most likely problem will be a defective water valve # 5220JB2008A . It could also be low water pressure but if the water dispenser is working ok, the pressure should be ok also. The water valve is available at the link listed below.

I already replaced the icemaker. It is an LRFD25850TT. After thinking about it, when I put voltage to the solenoid, it flowed water, but little pressure. I will check today to see if it indeed is receiving voltage during the cycle, but the solenoid is not opening enough to all enough pressure to fill the cavities. Oddly, it made 1 cube last night. Perhaps I have a defective solenoid.

Kris, the problem could be with the icemaker itself or the main control board. For more specific information, the complete model and serial number will be needed. Thank you for using Manage My Life.

I have an LG Bottom freezer, with the same problem. I traced it back ot the solenoid, which is not receiving voltage. When it receives 120v, it opens and flows water.

What sends the signal to it and where do I go next?

Thanks!

Having an icemaker is a great feature but when it fails can be very disappointing. There is also a valve located inside the door (see picture) that feeds both the dispenser and icemaker. If you are manually cycling the icemaker (holding the water level button for 3 seconds) listen for a humming sound, toward the end of the cycle. If you can hear this sound, it indicates the water valve is getting energized but not opening. The valve # 6877JB3036V in the door will need to be replaced. If you do not hear this sound, some voltage checks will need to be made. A technician will be needed to make these checks. I'm listing a site you can access, to have a tech come out. Here is a link for the website:
