Temperature display and control-kenmore fridge

[Rik]

 

 I have a Kenmore Elite (795.751193401) that no longer holds temperature nor does the display work anymore.  It started with the display not staying locked or holding temp now nothing at all displays.

and the food in the fridge freezes.

I replaced the main control board 

(6871JB1280C or L) in the rear of the fridge.  This did not solve the problem.

I then tried changing out the display control board

(6871JB1310A) in the front of the fridge.  The new part did not help the display come on.

Any help appreciated!

Your model didn't come up any where doing a google search. Used 795.75193401 to get some info. Since you have replaced both board with no success you probably have a broken wire some where in the harness.  Ohm out the wires from the display board to the hinge area, if those are good then hinge area to main board con6 pins 3, 4, 5, 6. Colors of the wires stay the same from display board to main module.
