Goodman Furnace: Data not yet on network
Data not yet on network on a Goodman furnace: No data, no run. Control comes up with an empty shared data set, so it will not fire. Almost always a new board or a fresh install. Model data lives on the memory card, not in the board. Right card, right model.
Applies to: 34.5 in chassis gas furnaces
Common causes of data not yet on network
- Control has no data on the network yet, such as after a new board or fresh install
- Memory card missing, loose, or not seated in its connector
- Card from a different model loaded by mistake
- Power cycled before the data finished loading
How to fix data not yet on network: step by step
- Power off before repair
- Get the memory card for the specific model. Wrong card, wrong data
- Seat the card fully, and confirm the model number matches the furnace
- Insert the card before turning power on
- Power up and let the data load. Give it a minute and do not interrupt
- Power off again. Card can come out after load and power-down
- Error clears once data is loaded and power has been cycled off. If it returns, recheck the card and the board
