Ann, Could you give us the make of fridge and year or year of Roadtrek? We would be happy to help but for future look up help, Chris Bryant has a blog with tons of stuff including some manuals.
So give us some make and model type info and someone will know the answer.
Learn how to post pictures too. There is a tutorial for posting pictures in Technology Corner I believe.
Actually it is Forum Technical Support and it is the third item, second sticky called, RV>NET Tutorials and FAQ's. There is more than one way to post in your text.
