Just after the winter, fridge was switched on and a popping sound was heard from the back. Now not working at all, and has been taken to a caravan garage,no voltage found running through it. I've contacted Dometic, as it was installed in the van I purchased, no warranty. They have given me links to places that might help but no luck so far. They have given me a parts place to contact. I'm thinking it's a fuse blown in the electric modular unit? However I wonder if anyone has any experience and better advice please.
