Goodman GMVC960803BN Error Code Ed6: Unrecognized Data ID
What Does Code Ed6 Mean?
Error code Ed6 on the Goodman GMVC960803BN indicates that the integrated control module encountered a data identification code in the shared data set or on the memory card that it does not recognize. Every legitimate memory card and shared data set for the GMVC series contains a specific data ID that tells the control module which model and configuration the data belongs to. If this ID is not in the control module's list of recognized IDs, the data is rejected and Ed6 is displayed.
An incompatible memory card — one from a different product line or a much older or newer generation — is a likely cause, as its data ID format may not match what this control expects. A corrupted memory card where the data ID field has been damaged or overwritten with invalid data is another cause. The control cannot use the data in either case.
The technician must obtain a memory card that is confirmed compatible with the GMVC960803BN. Contacting the Goodman distributor or technical support with the model number and control board part number will help identify the correct replacement card.
