Tis is the second time that I will have to replace this switch. Why is it faulty Model Norcold 12X-IMXX. The code comes up "LI" and it hapended in Palm Springs in January. We can bypass with a fuse for temporary use but will need this part again. Cost us $250 the last time. Thought there should be a warranty as this is a 2007 Winnebago Itasca Suncruiser. Nice fridge but sure wouldliketo knowif it is the heat that is causing the problem and how to fix
