Crock-Pot brand replacement parts can be found at the official replacement parts page on Crock-Pot's website. Universal replacement parts, which may be compatible with Crock-Pot brands, can also be found on Amazon.
Officially licensed products are easiest to obtain from Crock-Pots official website, but universal parts found on Amazon may be cheaper to purchase. However, there is no guarantee that these universal replacement parts will fit a Crock-Pot appliance exactly, so care should be taken.
Crock-Pot's official website offers a wider selection of parts than Amazon, sorted by the size of the appliance. These parts can range from the smaller 2.5-quart appliances all the way to the larger 7-quart appliances. The parts available are also further broken down based on whether the appliance has a manual or digital control type. The website even breaks down available parts by the number of servings the pot may prepare.
Replacement parts do not appear to be sorted by color, so care must be taken when shopping for things such as lids and cookers. As of 2015, some of the products listed did not come with pictures, with the image being replaced with filler text. However, clicking on a product shows which model number a given replacement part is for, making it easier to choose the right part.
