Our fridge was getting warm, called a repair man, when he came he took the back off the freezer and the coils had lots of ice on them. He check some things and told us it was the control board that was bad. He said it would cost $300 to fix. I thought maybe we could do it ourselves. I found the control board part on your site, now I am looking for directions on how to remove the bad one and install the new one. Can anyone help? Thanks.
