Goodman gas furnace code d0: No shared data loaded on the control board
Gas furnace, Canada and United States
The control board does not hold the shared data set for the furnace, so the furnace does not run.
This needs a licensed gas technician. There is nothing safe to check yourself. Leave the covers on and book a professional.
What causes it
-
The furnace has no shared data. A technician loads it with the memory card for the specific model.
How to read this code on your unit
The code shows on the two-character display on the furnace control board, which you can see through the sight glass on the blower compartment. On means normal operation. A blank display means the board has no power or has failed. A ComfortNet thermostat, if fitted, shows the same codes with a short message and uses EE for an internal fault.
