What is the difference between the Whirlpool AP3109393 ADC control and the AP3109394 ADC control? Are they interchangeable?
Answer Hello Rudetemp,
The exact differences are only known by the engineers who designed them. Since they are not interchangeable as they are not listed for any of the same models, they will have to have different defrost characteristics, especially since one is listed for larger cubic foot displacement units. This means that the duration between defrost cycles and the length of the defrost cycles have to be different because of the difference between the sizes of the units they are designed for. These type questions are best asked to the manufacturer who designed them. They are not interchangeable.
Not cooling, compressor kicking on, in the inside part of the freezer in the back it is cold, but the fan is not running. I have taken the fan out and tested, and the fan works fine. From the wiring diagram, it appears that I need to replaced"electronic defrost control", because theres a relay within that printed circuit board, and the diagrams have the fan running to that board. Also, the light does not work (new bulb, tested the switch), and that also runs into that board. Any additional ideas.
Answer Hello Boomer. Yes, if the board is not sending power to the fan motor, replace the defrost timer 4388931.
