Yes the control boards do fail quite often.The way they are designed they control basically everything.The first thing I would do is to make sure that you have power into the board and out of it,Check on the board to see if there is a low amp auto type plug in fuse in the board itself.These fuses typically will only be 3-5 anp so check to make sure it is good. If you have a volt meter you can trace the wiring from your ignitor to the board and have the heater calling for heat,that way you can see if you are getting power out of the board ,Also trace power into unit to make sure you have power coming in,Check for a flame rollout switch as most are resetable.I hope this helps you some. Thank you.
