My water dispenser was leaking water from behind the panel, the hose had popped out (2nd time this has happened. After opening the panel and replacing the hose, I hooked everything back up and the ice dispenser would not stop dispensing, it was getting a constant signal every time I plugged the cable back in. I took both boards out trying to find an obvious problem, which I didn't. Now I get no power to the dispenser at all when I hook everything back up. I'm not sure what parts to replace, the front circuit board, rear board or the harness cable. I'd rather not buy all 3 parts to find out I only needed one. Any thoughts?
