Atosa MCF8703ES Commercial Freezer Merchandiser Parts

Atosa MCF8703ES Parts List

Replacement parts for the Atosa MCF8703ES 55-inch two glass door merchandiser freezer, from Atosa's parts diagram (Rev. 01.2025). Item numbers match the exploded-view drawings, grouped by assembly. Atosa is moving to new part numbers; where Atosa lists one, it appears in parentheses after the part name, and either number can be used to order. Part numbers in blue link to the part's product page; parts without a link can be ordered by calling or texting (206) 419-5801.

Before you order: check the model and serial number on your unit's data plate. Atosa can revise parts between production runs, so send us your serial number if you're not sure a part matches. Refrigeration and electrical repairs should be done by a qualified technician.
