Ed4 Memory card data rejected

Medium severity Goodman/Amana *MVC96 (34.5 in. chassis)

What the control is telling you

The control refused the shared data set loaded from the memory card, so the furnace may act oddly or not run.

Applies to: GMVC96, GCVC96, AMVC96, ACVC96 (*BA, ComfortBridge)

Likely causes

Shared data set does not match this furnace model

Test and repair steps

Turn off power before touching wiring or the board.
Confirm the card is the right one for this model and reload the data.
Insert the card before power is on. Remove it only after the data loads and power is off.
The error clears once the right data is loaded and power is cycled.
