hermanmullins Report post Posted February 4, 2020 Ookpik, Welcome to the Forum. I myself have no idea what you speak of. So fi we could get a bit more information such as Make, Year & Model RV you are talking about someone with the same unit may had your same issue but just doesn't know the part number. Thanks and again Welcome Herman Share this post Link to post Share on other sites
