|Yes Poobah if the fan is not running right, the compressor could run 24/7, and with the new and better defrost timers, you could have more frost build up than if the fan was right. After the first defrost cycle however, the ADT will know there is more frost than normal, and put the defrost timer into a longer, and more frequent defrost cycle, and should correct any abnormal frost buildup. My crystal ball thinks it is the ADT that is bad.
