Parts for many old GE ovens are available on the official GE parts website, GEApplianceParts.com. To access illustrated assembly diagrams and check on parts availability for an oven, buyers can type a model number or part number into the search box on the GE site.
Replacement parts for ovens no longer being manufactured are still available for purchase. For example, all 131 replaceable parts for the discontinued XL44 Gas Range line of ovens are available, as of 2015. Some older GE parts have been assigned new part numbers. Links to purchase the updated parts are provided in the relevant parts lists.
