Low water pressure from dispenser and ice maker doesn't work.

could be frozen water fill tube to Icemaker. or solenoid water valve is not opening when ice maker calls for ice. there are 2 separate solenoid valves : one for dispenser another one for ice maker.

Used machine? If new seller needs to help. If under warranty check the MFG customer service number.
If used this may be the reason it was sold. If Used there is a possibility the water filter needs to be replaced. Yes they'[re expensive, but they can interfere with the process. Does the Cold water device work? Is there plenty of flow? If so it's not filter or pressure. If it barely comes out, then it's probably filter and may be the ice maker issue.

Hello John;

My name is Peter. I am a retired field service refrigeration technician.

Neither your ice maker or water dispenser work off your main control board.

There is only one reason that the ice maker will not fill and you water dispenser does not shut off immediately after the contact switch disengages.

Your problem is low water pressure. You have a bad water valve.
After time the water valve seals fail, metal form the water line or corrosion plugs the water supply valve. You need at least 60 PSI water pressure to shut off the water dispenser solenoid valve and at least 60 PSI to open the ice maker water valve and fight the long fill tubing resistance.


Check - Pull your unit out where you can get behind it. Turn power off to your unit. Turn the water valve off. With towels under the unit water connection and a large bucket ready, disconnect the water supply line. With the water valve shut off you will probably get a steady stream of low water flow. The valve is bad. If not, open the water valve with the water line in the bucket. Is the water flow 60 PSI? Probably not.

Use a hair dryer to completely dry the solenoid valve and electrical area before you plug your unit back in

You need to replace the valve.

Before you do the above. Just in case you move your unit check for a bend or closure in the water line.

Ice dispenser doesn't work

1. Dispenser control board

If the ice dispenser is not functioning at all the most likely cause is going to be the dispenser control board. The dispenser control board governs the major portion of the systematic functions of the dispenser and is less likely to be the issue if only certain components are malfunctioning. If the dispenser control board is at fault, it will need to be replaced.

1. Water inlet valve & low water pressure from house supply

If the ice dispenser on your refrigerator is not working properly, one of the first things to consider as an issue is the water pressure to your appliance. The ice dispenser cannot properly function with a psi less than 20. If psi is appropriate, proceed to replace the water inlet valve to correct the issue. You may also be dealing with low household water pressure. This low flow can be examined by using a water pressure test gauge. Once the household water pressure is resolved, you can double check your refrigerator connection to ensure it is now flowing properly and that the ice dispenser is functioning.

1. Water tube in door is frozen

If the ice dispenser is not working on your refrigerator, the issue could be a frozen water supply tube located in the door. Although this may be a tricky problem to locate, the first thing to do is find a connection point in the tube. After this has been found, attempt to blow air through the tube. If the air flows freely through the tube, it is not frozen and this is not the issue. If it does not, the tube is frozen and needs to be removed to thaw out. As it thaws, attempt to ascertain why it froze and correct the positioning of the tubing to prevent the issue from occurring again in the future.

1. Dispenser switch

If the refrigerator ice dispenser is not working properly you could be dealing with a defective dispenser switch. Activated by the dispenser actuator, the switches are responsible for numerous actions including ice cube disbursement, type of ice, and water controls. The switch can be tested using an ohm meter and should be replaced if it does not reveal continuity.

1. Door switch

If the refrigerator ice dispenser is not working, the functionality of the door switch can be inspected. This switch is responsible for turning on the light in the freezer and simultaneously turning off the ice dispenser when the freezer door is opened. If this switch malfunctions, it will show no continuity on the ohm meter and will require replacement.
Ice maker not functioning or producing ice cubes

1. Check connections

Check all hose connections to ensure that water is being transmitted through your appliance and there is no frost build up.

1. Feeler arm

Double check to make sure your feeler arm is not stuck or that ice cubes are not blocking the feeler arm's motion to produce more ice.

1. Ice maker heater

The heater may be stuck on. The heater comes on for 1-2 minutes to break cubes free from mold. If the heater stays on too long ,the ice maker will get hot and stop making ice. Carefully feel around the ice maker mold; if it is hot to the touch, the heater is on. This indicates that the ice maker is jammed, and it is better to replace ice maker than to try and repair it.

1. Water inlet valve

The water valve supplying the ice maker is a key component of the ice-making system. When the ice maker calls for ice, its switch closes an electrical circuit and energizes the solenoid-operated water valve. This allows water to flow through the valve and into the ice cube tray. The water is frozen into cubes, and the cubes are dumped into the ice bin. When this part is not operating correctly, a repair/replacement part may be needed.

If your house water supply to the refrigerator is poor it is most likely the cause of the water dispenser and ice maker not working. If you hear the water valve humming when the water dispenser is depressed and no water is dispensed it is most likely poor or restricted water flow to the refrigerator.
If you live in an older home the water supply shutoff valve to the refrigerator is usually in the basement or under the kitchen sink. Many shutoff valves are called a saddle valve and the valve is secured onto a cold water pipe and as the valve is turned clockwise a pin punctures the water pipe allowing water to flow. Saddle valves often become clogged with minerals and can completely block water flow to the refrigerator,. If the valve is corroded on the outside it should be replaced. Ice maker installation kits are available at most hardware stores. Copper water line kits are preferred. Cost is under $25.00. If the Saddle valve is in good shape they can be taken apart and cleaned. Be sure to shut off the main house water and drain pipes before attempting to clean.
Newer homes may have a water box in the wall behind the refrigerator. Sometimes these can become clogged with mineral deposits as well.

Hope this helps.
Mike

Disconnect the ice maker line from the valve and watch to see if it has a slow drip. It doesn’t take much to eventually block the fill tube.
The valve can leak because of sediment in the water preventing it from closing or low water pressure.

You can thaw out the fill tube and replace the inlet valves.

If your ice maker is making full size cubes then it should one of 2 problems.
The water valve on the bottom back of the machine is a dual valve. One side feeds the ice maker, the other side feeds the water supply.
1. The dual water valve. is going bad. The water side is malfunctioning.
The dual valve must be replaced.
2. Your model should have filters for the water dispenser, and need replaced.
Try changing the filters first.

Is the freezer at least 10 degrees? Is there water in the ice mold? If not put some to see if it will harvest after it freezes. If no water getting to ice mold Try swapping the wires on the dual water inlet valve. Then try the water dispenser. The water should go to the ice maker. This will tell you weather or not the ice maker valve is working and if the line is clear.
