I agree with this.  It's probably too late for this install as you already have a new board (unless you can return it?), but for those reading in the future that need to replace a furnace board, the Dinosaur boards are the best option.  In particular because they have a significant improvement in the design compared to many of the original hydroflame boards that prevents the battery from running down once the battery voltage runs below a certain voltage.    The original boards would keep running the fan and re-trying the spark/igniter no matter what the voltage is, but once the voltage goes below a certain level as the battery gets flat the igniter fails to make a spark.  I believe the igniter needs a voltage above a certain level in order to ignite the gas.  So if the voltage is low and the spark won't light the gas then the fan keeps running until your battery is totally dead.  Dumb design.  The Dinosaur board is smart enough to stop trying and not kill the battery.

i also have a hydroflame fa 7615 with a bad board and i, having a hard time determining what is the correct Dinosaur board i can replace it with. all my searching keeps  dead ending in uncertainty.
