The frost was all over the ice compartment - like a snow storm in part, but a glacier in others.
Now (after I replaced the defrost heater) it's dead. No cooling at all. Completely warm. No lights on the front panel. The compressor is room temperature and the fan is motionless. The only thing that is working are the inside light bulbs.
Try this first, unplug the unit. Remove the kickplate in the front under the doors. I believe your model has screws at the ends of that panel. There should be a connector under there coming from the freezer door. Take a wire brush an old toothbrush or something and clean that connector up really good. Put it together and give it a try.CLICK TO ENLARGE
If that did not work check the red and black wire at that connector for 12 volts dc. If you have no voltage replace the main control board. If you do have voltage replace the dispenser board.If you found my answer satisfactory please login if you are not already logged in and please leave an ok or better rating so that I am compensated.

Will try that now. Thanks.
Connector was on top, not the bottom. It looked good, but in any case I cleaned it up.
Reading varied by 4 and 12VDC. Shopping for replacement dispenser board now.
I understand Michael,
I am sorry its not shown on the diagrams where the connector is. Most are on the bottom. WR55X10561 is the part number, its off white in color.
Replaced dispenser board. No effect. Still just as dead as before.
But you did have 12 volts at that connector? Look and see if there is a broken wire going into the hinge.
Wires looked fine - like new. Volts varied between 4V and 12V (see above)
I can test for continuity between the hinge and the dispenser board connectors.
Continuity was fine.
It WAS the main board in the end. I bought one and replaced it, and now the fridge is working again.
