Apazm1, unfortunately your main control board is the culprit for your woes. The part number is WR55X10552 and retails for ~$115.00. There's good news, though! It's readily available, (all the appliance parts retailers have them) AND they are easy to install. After you have the new part in hand, open the box and read the instructions CAREFULLY. These boards have been modified from the original OEM's and work on all fridges like yours. UNPLUG YOUR FRIDGE! Pull it away from the wall, locate the aluminum panel that covers the computer and remove it (4 screws). The board is held in place by 4 white clip tabs. They poke through the board at (roughly) the 4 corners of it. Look closely at these with a flashlight... you'll see where you need to squeeze them with a pair of needle nose pliers to release them (squeeze the clip and pull that area of the board at the same time). Then remove all the connectors from the board. Now snap the new board into place and reconnect all the wires. This is where you need to pay attention to the instruction sheet! Look out for that white "jumper" in "pin #2"... if you don't get this right your fridge won't work right. Here's the reason I know it's the main board and not the board behind the dispenser area... the dispenser board is low voltage, the main board is high voltage. The dispenser board only sends a signal to the main board. From there, the main translates this input into a high voltage command for the component you have selected (water, ice crushed, cubed, etc...) The components that aren't working on your fridge are high (120) voltage parts controlled by the main board... ergo, failed main board. Hope this helps! Let us know how it goes, will ya?

We replaced the main board as you suggested. There was no white jumper in pin #2. We hooked up the board and everything else works on the reftigerator except it still does not dispence water or ice. It does not appear to reset the water filter like it did before this problem popped up. Can you suggest another fix. We have just replaced a $100 board and are right back where we were.
