The water dispenser keeps running full blast even after the switch is released. Have to open freezer door to stop. I had to shut-off the water to stop dispensing! The light on the dispenser is permantly ON although the switch is set to "OFF". Could it be the dispenser control board or the inlet water valve? Can I purchase a repair manual for this unit? Hard to understand how to replace the dispenser control board if I have too.
This issue would be more likely to be caused by the water valve not closing. If you disconnect the wire harness to the water valve for the dispenser and the water continues to flow then the valve is bad. If the water does not continue to run then the board would be the problem. There is not a service manual available for this unit. To remove the dispenser control board, there is a cover plate over the dispenser controls that you just pull on. This is not the trim that is around the dispenser but where is has the water and ice indicator. Once this plate is removed you will take the screws out that hold the control assembly in place and disconnect the wires to remove.
The ice and water won't dispense and the temp display in the refrig section is unlit. Is it the dispenser control board?
This issue would most likely be caused by a main control board issue rather than a dispenser control board.
