Eight years ago I remodeled our kitchen including all new cabinets etc. At the same time I built matching door fronts for our side- by- side fridge. The kitchen cabinet doors are 3 1/2 inches thick so I built matching `doors`for the fridge out of the same material but made then only 3 in thické. I fastened them to the fridge doors using Sikaflex 252. Its the same kind of adhesive they use to glue in car winsheilds. The inportant thing is that the fridge doors are flat. And because the panels are NOT removable it is VERY important that the door pulls are mounted very securely. At any rate the panels have been on the fridge for eight years with no problems whatsoever and look like all the other cabinet doors. I can send pics if you like.
