Dottie, since the Prowler is not a Forest River product, nor have i ever seen any FR product with a Magnavox fridge, you probably won't find much help here.
you'll probably get more help at a Fleetwood owner's forum or try RV.net's TT forum.
of course, someone here might have owned an old Prowler and be able to help.
otherwise, it'll only be generic suggestions.
