Goodman GMVC960803BN Error Code Ed1: Invalid Data on Network
What Does Code Ed1 Mean?
Error code Ed1 on the Goodman GMVC960803BN indicates that the integrated control module received and rejected the shared data set from the memory card during programming. The control module performs a validation check on the data and will refuse to accept configuration data that was not intended for this specific furnace model.
Memory cards for the GMVC series are model-specific. Each card contains a shared data set that defines airflow profiles, motor operating parameters, and system behavior tailored to a particular combination of heat exchanger size, blower motor horsepower, and staging configuration. Using a card intended for a different model — even one in the same GMVC96 family — will cause the control to reject the data and display Ed1.
The resolution is to obtain the correct memory card for the GMVC960803BN specifically. Contact the Goodman HVAC distributor, the parts supplier who provided the replacement board, or Goodman technical support to get the correct card. The installer or technician performing the board replacement is responsible for ensuring the correct memory card is used.
