I was having a problem that would light burners 3 times then go into lock out, when tring to check the flame sensor the lead was contacted with ground acidentilty, it then gave a code for revesed voltage, since the dia light is now on for 1sec then off 1sec. Im tring to figure out if i damaged the board or what could be the prblem, thank god I have a wood stove to stay warm.
allmost forgot that it did give a rollout code the very first time i started it this year but hasnt given it since.

What does the on 1 sec and off 1 sec indicate? Is that the reversed polarity?
