Changed control board today. ice maker is running but not producing ice. the old board had a connection for the door switch and the new board does not. does that matter.

It is located right below the top cover. You will probably have to take the door off to remove all the screws that hold the top. The control board is located there and the problem is either the connections on the side of the grid cutter wires, the plug in near the cutter inside the bin area or the transformer on the control board. You can probably get a price for the control board if you take your model number and go to Searspartsdirect.com and find the control drawing and you should be able to order a new control board with a credit card and have it delivered to your home.
Hope this helps

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.

see this causes and fix it. God bless you

Makes to much ice or won't shut off.

Check shutoff arm. This may be hung up on ice or food item.

Makes no ice.

Check shutoff arm. Check to make sure it is getting water, check water solenoid. Check water supply line it may be frozen or plugged up. Check freezer temperature to low of a temperature could cause the line to freeze up. Check for power at motor. You will need to remove the ice maker. Find the leads that go to the auger and connect a voltmeter. Press the dispenser lever you should have power if not replace the control board or micro switch. Check control switch or microswitch. Put icemaker in test mode. Only some are equipped.

Ice cubes to large or small.

Adjust size by removing cover and turn adjustment screw + or -. Check water solenoid. Check water supply line. Make sure it is level.

Ice tastes bad

Clean ice tray. Check supply line. Check water solenoid. Change filter. Run at least a 3 gallons of water thru the line after replacing filter this will flush all old water.

Ice is discolored.

Check water solenoid. Check supply line. Change filter. Clean ice tray. Run at least a 3 gallons of water thru the line after replacing filter this will flush all old water.

Most ice maker problems require either replacing the ice maker unit or the ice dispenser control board or micro switches.

For now unplug the pin plug at lower freezer door hinge and disable the dispenser control board until we see if the keyboard or the dispenser board is at fault. Sea Breeze

LG has problems with there ice makers. if is less than a year old it is under warrenty--even if you dont have a reciept. sounds like the ice maker needs replaced. i have replaced several that were less than a year old.

Open up freezer door look at ice maker. The wire is the on/off switch. If wire is up push down to make ice. The wire runs the length of the ice maker and does not take much force to move.

Good luck

You either have a bad interface board ( touch board ) or a bad main control board . You would have to go into the test procedure from the touch board to determine which is bad . The more I think about it though , I tend to lean towards the main control board . Once you get into the test mode , 0 and 4 would test communication between the 2 boards .

The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.

Hello jitkagardner,
Welcome


You said, The ice maker in my whirlpool gold refrigerator Model No, GR2FHTXTBOO, is not working.

How old is the fridge?
When have you last changed the water filter.
Should be down below at the front grille!
Try these tasks!

If the ice maker is not producing ice or not enough ice
Refrigerator connected to a water supply and the supply
shutoff valve turned on? Connect refrigerator to water
supply and turn water shutoff valve fully open.
• Kink in the water source line? A kink in the line can reduce
water flow. Straighten the water source line.
• Ice maker turned on? Make sure wire shutoff arm or switch
(depending on model) is in the ON position.
• New installation? Wait 24 hours after ice maker installation
for ice production to begin. Wait 72 hours for full ice
production.
• Freezer door closed completely? Firmly close the freezer
compartment door. If the freezer compartment door will not
close all the way, see "The doors will not close completely."
• Large amount of ice recently removed? Allow 24 hours for
ice maker to produce more ice.
• Ice cube jammed in the ice maker ejector arm?
Remove ice from the ejector arm with a plastic utensil.
• Water filter installed on the refrigerator? Remove filter and
operate ice maker. If ice volume improves, then the filter may
be clogged or incorrectly installed. Replace filter or reinstall it
correctly.
• Reverse osmosis water filtration system connected to
your cold water supply? This can decrease water pressure.

Let me know how it goes!
