From researching this site, I think the Adaptive Defrost Control Board needs to be replaced in my refridgerator. How do I remove the ice maker in this model to get to the area that the ADC board is located? Which screws do I remove? There are many and I can’t tell which ones are holding it in place. Thanks!

Not sure why you want to remove the icemaker as the ADC (Item 23 in Section 5) is in the fresh food section.
The following manual should help, the control area looks the same as yours.

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.
