Nothing happens at dispenser. Unplugged connector on top of door, left disconnected for 1 hour, then plugged back in. Dispenser works for brief time, then stops again. No lights at all. Ice maker working fine.

You have 2 separate valves, 1 for the water dispenser and 1 for the ice maker. (otherwise your ice maker would overflow every time you got water from the dispenser and your dispenser would flow every time the ice maker went to refill.) They are fed from the same tubing.

The cube/crushed ice motor is completely separate from the ice maker itself and should have absolutely no bearing on the water flow.

You have narrowed down the problem quite nicely to the ice maker water valve. There is one more thing to check though, the connector. There should be a multi-contact connector from the ice maker to the back wall of the freezer, usually 6-9 wires. Pull that apart and check the cord side (ice maker side) for any corrosion. BE CAREFUL NOT TO TOUCH THE OTHER SIDE AS THERE IS LIVE 110V!!! If you don't see any corrosion, still try try disconnecting and reconnecting 5-10 times and see if that solves your problem. If you see corrosion, unplug the refrigerator before working on the back wall part of the connector. [This connector besides powering the ice maker also allows the ice maker to control the water valve which can't be inside the freezer]

I had a GE Fridge at one time and had issues like yours.

If you disconnected the connector at the door that supplies the dispenser with power, you would not measure any voltage on the dispenser side, only on the 'fridge' side. Measure the power with the connector connected, but that may not tell you a lot, unless you have the service manual.

If you push the water dispenser and you do not hear the little valve kick on behind the fridge, suspect a couple of things. A faulty inlet valve (usually located lower rear of fridge on backside). It may be disconnected. Had this happen once on a new fridge - it had been disconnected from the factory.

You may have one problem or two issues, but let's continue...

Do you push the ice dispensor and nothing happens? Or are you telling us that the dispenser works but there is no ice? The faulty valve mentioned above will prevent ice dispenser from filling to make ice.

Also, there is RESET button hidden in the freezer a well. I can't remember where it is but the little arm to make ice has to be in position to tell it to make ice, and you have to follow the procedure in yourf ridge manual to reset it. It's

Another problem I encountered, but this was just with the cold water dispenser, was that the water line would FREEZE in the fridge door, preventing water from getting to the dispenser and my cup. It wold make ice but no water. In that case I had to get a small squirt bottle with a long nose on it and shoot hot water up into the dispenser nozzle to clear the ice in the line. That only happened a couple tines a year, though.

Need Help let me know, Thanks Sea Breeze

Most of the time this is a dispenser housing issue. Remove the dispenser tray from washer and make sure it is cleaned very well. In the more serious clogs, you may need to clean the hose from the dispenser to the drum.

1. Make sure the detergent dispenser drawer is opening. This issue occurs due to jammed soap dispenser. Dispenser Distribution System is located in the top left corner of the washer. The system consists of a motor that turns a cam gear. The Detergent Dispenser Assembly is located under the washer top. Begin by removing the washer top, console and front panel.
2. Separate the water inlet and window washer tube from the boot. Pull the water inlet tube from the outlet connector of the detergent dispenser. NOTE: When reinstalling the water inlet tube, wet the water inlet gasket on the detergent dispenser with water only. Do not use any other lubricant. Align the tab on the water inlet tube with the indentation on the dispenser connector and slide the tube onto the detergent dispenser assembly.
3. Remove the screw securing the front of the detergent dispenser assembly to the top front frame member.
4. Disconnect the vent tube from the detergent dispenser assembly. Remove the screw securing the detergent dispenser assembly to the top left frame member. Slide the assembly back slightly and lift the assembly out.
5. To remove the detergent dispenser motor assembly,disconnect the cam follower spring and lift the cam follower from the diverter cam and rotate the diverter cam clockwise to access the motor mounting screws. Check for all the connections to the dispenser motor or anything obstructing the dispenser drawer functioning.
6. Pull the diverter out and clean it, including the shaft, spring, etc.

possible bad dispenser board

Remove the top freezer door hinge cover and disconnect the plug there . This will remove power to the dispensor . Remove the dispensor grill , and also the 2 screws at the bottom of the dispensor front . Lift the front up and out , and remove the plug on the front . You should now see the white switch bracket . On the left side , is the ice dispensor motor switch , when usually , one of the spears holding the switch breaks off , not allowing the ice dispensor to work . If this is the case , the part number is 2180226 . Only held on by 2 screws . When/if replaceing , be sure to put the plastic spacers in the correct position next to both switches , and be careful not to break one of the spears , holding the switches .

leaks are usually from valve /dispenser area on top left or from door boot. to check valves open top cover by removing 2 or 3 torx/ 1/4' screws at rear and slide back. check underside of dispenser for cracks, check rubber hose connecting valves to dispenser.
to open front and check around boot, remove top cover, remove screws beside dispenser opening (remove drawer) snap control console off starting at dispenser side. On older non teardrop front disconnect and remove interface cables from ccu at rear (ribbon cable in clips on right side. On new teardrop models remove teardrop by unsnapping at top then work down carefully, then unclip console starting at left, disco cables at right side of interface. remove lower kick panel with 3 screws on bottom. then remove 2 front panel screws. remove 2 door lock asm screws and spring clip around boot, then 2 front panel top screws. panel comes right off, carefull of boot. door lock stays behind.

Just let it defrost 2 more hours.

More than likely, your water line is freezing up in the door. You can remove all of the ice cubes and lower the freezer temp to about 3. Leave the freezer door open for about 5 minutes or so and if this does not work, leave the door open a little longer. Also, disconnect the water line at the base of the freezer door, near the floor, and press the dispenser lever. If you have water there, you most likely have a frozen line in the door. Changing the water filter often will help but it is not the answer and is can get quite expensive. By the way, Make sure to hold the dispenser lever forward for at least a couple of minutes each time you test for water flow. If you do not get water at the connector at the base of the door after you have disconnected the line, you have a problem with the valve in the back of the refrigerator.

1. Remove the switch cap and unsnap the two (2) tabs at the bottom of the front cover from the
housing first. Pull the bottom out and lift and the front cover from the housing. (Fig. 27)
2. Remove the two (2) hex-head screws securing the metal control panel cover to the dispenser
housing. This will also free the control bracket from the housing although it will remain tethered
to the freezer door by the wiring harness. (Fig. 28)
3. Disconnect the wiring harness connectors from the terminals
on the switches and light fixture in the control bracket.
Removing the Dispenser Assembly
1. Do the previous three procedures.
2. Remove the eight (8) hex-head screws securing
the dispenser housing to the freezer door. (Fig. 29)
3. Carefully pull the housing from the door.
4. Pull the water supply tube from the top of the dispenser housing.
5. Pull the wiring harness leads from the dispenser housing.
6. Disconnect the wiring harness connectors to the electric
foil heater that should get you in there
