Rich D. for Model Number KSSC48QTS02 I'm having trouble dispensing ice from the door. When motor that opens the chute flap turns on, the LEDs in the dispenser area dim to the point that they are barely visible. The motor slowly opens the flap, but sometimes not completely. When the motor stops, the LEDs turn back on. After a few seconds, the same process happens as the motor tries to close the flap - sometimes it gets there, sometimes not. If I happen to be dispensing water when the close sequence starts, the valve shuts off too while the motor is running. The refrigerator display/lights are unaffected. I tried replacing the flap door motor but nothing changed. I suspect a weak power supply to the motor/valve/LEDs. Tracing the wire harness from the motor/dispenser board and looking at the cabinet wiring diagram, it looks like they are driven from the Electronic Control board marked 6105040 part #AP6007276 on P5 connector. I''m not sure if the problem is on that board or possibly the power supply feeding the board. Since the control board is $266, I'm wondering if anyone has seen anything like this and could give me their thoughts before I buy one.
Answer Hello Rich, you are correct that the dispenser is controlled by control board WP2318054. However, this model being an older side by side model the wiring in the freezer door for dispenser operation, especially where it exits the door hinge is suspect, and more likely to be causing the symptoms you described. Do a visual check on the wiring and if you have a multimeter check the wires in the door end to end for shorts/continuity. The power supply and control board are usaully not at fault. Read More...
