I have replaced the board ( 2 different New boards)...Replaced damper, built in thermal sensor....Still same problem....Freezer works fine....Fresh food side pulls down to about 25 degrees, no matter where you set temp.....Damper works fine when you first turn on refrigerator...after about 1-2 hours...the damper seems to stick....you can move easly with your fingers but it wont move on its own by pressing and releasing the light switch on the fresh food side....I had another tech look at it...he couldnt understand what was going on either....anyone have any suggestions?
