Amana AMVC960803BN Error Code Ed6: Unrecognized Data ID

What Does Code Ed6 Mean?

Every legitimate shared data set and memory card for the Amana AMVC960803BN carries a data identification — an ID that tells the integrated control module which model and configuration the data belongs to. Ed6 ("Unrecognized Data ID") means the control read that identification but does not recognize it, so it will not use the data. This is distinct from rejecting the data's content: here the control cannot even place the data ID as one it knows.

The usual cause is a card that does not belong to this control — for example a card from a different product line or a much older or newer generation whose data ID is not on this control's list of recognized IDs. A corrupted card, where the data ID field itself has been damaged or overwritten, produces the same result. Because shared data is loaded during a board replacement, new installation, or reconfiguration, Ed6 appears right after one of those service events.

Seeing Ed6 among its siblings helps target the fix. Ed0 (Data Not Yet on Network) means no shared data is present at all. Ed1 (Invalid Data on Network) and Ed4 (Invalid External Shared Data) mean data was present but its content was rejected as not valid for this model — typically a wrong-model card. Ed6 is the narrower case of the data identification not being recognized in the first place. Ed5 (Invalid Downloaded Firmware) is unrelated to the shared data; it concerns corrupted control firmware and is not fixed with a memory card. For Ed6, the remedy is a confirmed-compatible, model-specific card.

Until valid shared data is loaded, blower codes can follow, since the motor parameters live in that data. Eb2 (Blower Motor HP/ID Mismatch) can appear when the horsepower the data specifies does not match the installed motor, and Eb7 (Incomplete Parameters Sent to Motor) can appear when the motor never receives a complete parameter set. Loading a recognized, correct data set for this model normally clears those as well.

What You'll Notice

• Programming with a memory card fails and the display shows Ed6, typically during a board swap or new install
• The furnace will not complete commissioning and does not run normally after the data load attempt
• The card being used is from a different product line or a different generation than this control expects
• The code appears immediately after a technician inserted a memory card to load data
• Re-inserting the same card and cycling power does not clear the code

Common Causes

How This Is Diagnosed

A technician confirms the exact model number and control board part number, then checks whether the memory card being used is the one specified for this model and generation, since an out-of-family or wrong-generation card is the common reason its data ID is not recognized. The correct, confirmed-compatible card is obtained from the distributor and the transfer is re-run on this chassis by seating the card before power is applied.

If Ed6 persists with a card that is verified correct for the model, the technician treats the card as corrupted — its data identification field may be damaged — and repeats the load with a replacement card. Identifying and sourcing the compatible card and loading it are technician and installer tasks, not a homeowner procedure.

When to Call a Professional

This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:

• Ed6 appeared while loading data during a control-board replacement, new installation, or reconfiguration
• The memory card may be from a different product line or generation than this control expects
• You cannot confirm the card matches this furnace's exact model and control board part number
• The correct card is being used but Ed6 keeps returning, suggesting a corrupted data ID on the card
• Blower codes such as Eb2 or Eb7 appear alongside Ed6
