Default Installed new Atwood water heater circuit board

I just replaced an Atwood circuit board with Atwood 93865 from American RV in Azusa, CA. Cost $122.52 including f'n Ca tax of $9.38 and shipping of $5.95. At first,heater didn't fire up, though I could see ignitor sparking. I finally discovered the problem: the circuit board connector was made for a thicker wafer on old circuit board, so contacts were not secure. I squeezed contacts closer together to make them tighter, and voila, it works great. I also had to move circuit board over a bit because mounting holes didn't match original. Be careful if you do this, because it might be possible to puncture tank with drill or screw. Also it might be best to not stand by heater if switch is on inside while connecting circuit board. I did and experienced somewhat of a small explosion.
