The German appliance manufacturer, Bosch, does not appear to sell parts though retailers. The only way to purchase accessories and replacement parts for their refrigerators and other equipment seems to be directly from the manufacturer, via their website.
To find parts on the Bosch website home page, click on the Accessories tab. On the Parts & Accessories page, select Refrigeration. On the Refrigeration page, the shopper may browse through and order general accessories, such as water filters, drawers, shelves, and egg racks.
For model-specific parts, such as circuit boards, control modules, and compressors, click Shop for Parts by Model Number. Here the shopper will need to enter the model number of their refrigerator in the search field, located in the upper right corner.
If a repair requires installation of an electrical or mechanical component, or recharging of the refrigerant system, a certified technician is highly recommended. To find a local repair technician, on the home page click on the Support tab, then under Type of Dealer, select Authorized Servicers, and enter the relevant ZIP code. In the event that there are no Authorized Servicers in the local area, Bosch provides a toll-free telephone number that appliance owners may call to help locate a refrigeration repair agency.
