Problem started with the ice dispenser, by pressing the level, a second later, what seemed to be an overload, will cause the display to go off and whole unit to be unresponsive, and then come up lit minutes later. After few similar incidents, eventually the front display stayed dark and nothing was operational, from the control/dispensing unit. After researching,the front display panel gets power from the main board, so I did changed the main board, but now the display is still dead, and the only thing working are the lights, no running compressor. Since then I put back the original main board that at least keeps the refrigerator running, but without dispenser or temp. controls/display etc. At last,after awhile, having the refrigerator operational but without lights, and using the ice maker without dispenser I did replaced the front panel display but did not change anything! So here I am looking for professional help. Again the new main board not only did not fix the problem, but it did not kick the compressor on either, and the new front control panel did not help, btw solenoid is fine. Thanks in advance
Answer Hi. You also need to note that the fountain control assy. gets its power through the connectors above the freezer door hinge cover area. Quickly check to see if there are any connector pins burnt or not connecting. Jumper these if necessary and correct all unclean ground screw connections. Make sure the wires are not twisted together4 and pulling the connectors apart as the door opens and closes. The same as all electrical pin connections at either the controls and the main control board. Use a magnifying glass to see if the female connectors are not bent out enough to make tight contact with the boards. Use a pick tool to reach in and pull the female inverted pins out. Small but major part issues. The freezer door switch part #  has to open and close the power going to the fountain control board. We will send the control board instructions as the connections are the same but may be in a new area-thus-a possible misplaced board connection (unmeanig ably). Since the solenoid is an output voltage, your concern will be if any wire is pinched together or shorted to the bare cabinet. Look for this as well at all main control board connections. You are correct with a power supply issues with the initial fading of the fountain control board functions. Use a ohm meter to make sure all connections are not shorted to the cabinet one at a time. You will compare the main board output voltage's. There is a fountain lighting board part # WR55X10899, separate from the fountain control board. We will email information as well. Thank You.
