What is the difference between the ADC III board and the ADC IV board? I know that the board is wired differently between the ADC II and the ADC III, but what was the upgrade on the ADC IV?
ANSWER Hello Temprude,
The engineers eliminated the use of one of the switches to prevent a short defrost cycle which was causing frost to accumulate and prevent the proper cooling of the fresh food side.
