my goodman furnace led circuit board flashes constantly but nothing happens as far as the furnace trying to start. The blower motor runs constantly but nothing else happens. It has been setting idle for about 5 years. Any ideas?

No, That's what is what is confusing me because the code is saying a polarity issue but nothing has been changed. thanks, Rick

Thanks...you are correct, it is polarity.... but that code is more for initial installation. In the event the polarity code changes, it is because of a bad circuit board.

 

The board is no longer recognizing the power. The circuit board needs to be changed.
