Atwood is now owned by Dometic. If you have the owner manual, there may be an exploded parts diagram in it. If not, get your model number and start searching on google for a part number. Then start searching on google for that part number. You may get lucky and find one on ebay. If you get desperate, try to contact the manufacturer, usually by email with the info. Last desperate chance will be to contact a vendor that handles Dometic/Atwood. It is a long and difficult process, but about the only way to do it. Unless someone on here has an old one in the garage they want to sell.
