Two convection cavities of 4.8 cu. ft. each sit in the DOB30T977D’s 51-1/2-inch tall chassis. Dacor’s manual prints the same information-code table as the single oven, so a C-20 does not say which cavity’s sensor has failed; that is found at the connector.
The upper door on double ovens takes most of the opening and closing, and its hinges wear first. A door that no longer closes square can also trigger the lock code during self-clean.
