Refridgerator too cold adjustment no good.

First I replaced the Defrost Thermostat on the coil and this did not fix the problem. So I ordered this new ADC (Adaptive Defrost Control)board.
It is not identical to the first ADC board and at least one feature the old ADC did was deleted from the function of the Fridge. Not sure why?
Because the board were different a new wiring harness was provided.
Step 1. Unplug the unit and remove the water filter.
Step 2. Remove the covers off of the unit on the top of the fridge using the 1/4" nut driver and a 1/4" deep well socket with extension for the deeper inset fasteners. This exposes the wiring harness and the ADC board as well as the temperature controls.
step 3. Remove the screws for the ADC on the cover and remove the wiring harness from it. No need to note the wire's positions as the new ADC uses a different connector.
step 4. As you remove each connection of the wire harness from the unit replace that connection with then new harness connector to eliminate any confusion. Do each one. One by one until the old harness is completely loose and the new harness is completely installed.
step 5. Install new ADC which in my case was now enclosed in an orange case. Unlike the one I removed that was and open pcb.
Step 6. Replace covers using the 1/4" nut driver and 1/4" wrench.
Step 7. Replace filter and plug in unit.

Apparently there have been 4 versions of this ADC board through the years. My fridge was built in 2003 not long before I bought it.
