Goodman Furnace: Invalid memory card data
Invalid memory card data on a Goodman furnace: This one shows up when the control module looked at the shared data set on the memory card and refused it. Usually the card doesn't match the furnace model, or the data didn't load right. It's an easy fix if you've got the right card.
Applies to: 34.5 in chassis gas furnaces
Common causes of invalid memory card data
