We had a repair man out to fix our Freezer who wanted $225 for the control board plus labor, found the part on your site is there a vidio or instructions on how to replace the control board.
To remove the control in order to replace the control board you will need to peel off the overlay/keypad for the control. Behind the overlay there are 2 screws that need to be removed in order to get the control panel off and to install the control board. You may want to order the overlay at the same time you order the control board if your are needing the display control board. There is a main control board that is located under the unit and can be accessed from the back of the unit that they may have been referring to as being the issue. Here are the part numbers for each component, the overlay is part number 297072600, the display board is part number 216944300 and the main control board is 216979700.
