Using a screwdriver, remove the screws so that you may remove the control board from the
door. Place these screws in a safe place for later use.
Remove the existing temperature control board.
You will now find 3 terminal wires that connect the control board to 3 important functions; one
for the interior LED light, one that allows the power button to function, and the NTC wire.
