In-door dispenser not dispensing water or ice

The repair was simple. The electrical connector to the dispenser was corroded. It was difficult to diagnose, however, and I replaced the main power board (refrigerator), dispenser door solenoid, and the defrost heater before I found the problem. If I had checked this connector and looked closely I would have noticed the corrosion. Live and learn. The connector is behind the bottom refrigerator grill on the left side, right under the dispenser. I recommend checking this before anything else if your dispenser quits. Our lights were working but not correctly. It was a bad connection, and intermittently gave water and/or ice. Once we fiddled with the wire we saw corrosion around the plastic connector and then the wire fell apart in my hands. By the way, the defrost heater was on its way out and the dispenser solenoid was rusted out, so it was just a matter of time for those parts. I'm glad I'd replaced them, even though they were probably still functioning OK. I did have some frost build up in the freezer around the ice maker, so I surmise that the defrost heater was going. Good luck with your repair! BY THE WAY, the dispenser electronic control board that I'd received was the wrong part! I will save a lot by sending that part back because the original one wasn't even bad.
