I can't find the Adaptive Defrost Control board on any diagrams for my Maytag french door refrigerator model MFF2558VEW1.  Where is it located so I can change it out?

The defrost is done on the main control board.

When I replace this board I always replace the thermistor. When replacing this board you will have to program the units code number in. It's not that complicated. There is a tech sheet with the part..pain in the ass.

Thank you for the reply.  I had a repair tech come over and show me the location of the ADC board in my refrigerator to fix the warm refrigerator/cold freezer problem.  It's behind the temperature setting LED displays at the top inside of the fresh food area behind the French doors.  You have to remove the light cover and bulbs and push the front of the unit back and down to remove it.  Inside is the Control Board for the whole refrigerator/freezer. 
In my case, the Control Board Troubleshooting Guide included on the tech sheet (found under the front of the freezer drawer) instructs you on how to check everything EXCEPT ITSELF for problems!  The tech said that this is the first thing he changes-out before anything else because it it the easiest fix for a defective defrost system on this model (MFF2558VEW1) Maytag.  He was right of course, and now I again hear the happy sound of sizzling condensate water as my machine returns to a normal defrost sequence.
I'm making notes on the guide to remind me for next time; and he said there probably WILL be a next time with this crappy board.

The LED's are on the same board. Everything is run of this one board.

Just as I posted above, your model uses control board part # 12868513

Yes, you were correct, that's the one!  I didn't know where in the machine to find it.  I do now.
Now it's time to load more cold drinks in it and keep cool.  Summer here goes on into October and I need the ice!
Thanks again!

Also good advice from Harold.
I replace a ton of these board as I'm sure other techs do too.

Harold do you change both thermistors even if they pass in the diagnostic test ?

Yes. I was having some call backs. This evap coil is a paiN to get to, so I want to make sure I'm done with it. Just because it passes the test does not mean it's good. This test does not check ohm value.
