This controller eliminates all of your existing Norcold or Dometic controls. So that means that your front display panel, your interior light, and your rear control board will no longer work. This new controller has its own temp control device and thermostat, as well as a light bulb that is motion activated. To mount this new control assembly, you will need to remove the existing interior fin fan and all wiring associated with the fin fan that is clipped to the fins inside the fridge. Then mount the new controls in the exact spot that the fin fan was at. The wiring will be run thru the defrost drain hose to back side of the fridge. This controller is for Dutchaire 12V units only, we have another controller available for 120V units. This will not work on a Gas/electric unit.
