I've had my PI40 since 2003. Replaced the control board in 2009. Recently the stove will go through the ignition sequence twice when it fires up regardless of it turning on by thermomstat or button push. FYI, not sure if this is related, but I also had to Dremel out the bracket that holds the burnpot as well as shift it 1/4 of an inch to the right. This has greatly increased the chance of it igniting(basically 100% now.) Not sure why it is going through the ignition sequence twice. I have cleaned all of the sensors on the stove, especially the proof of fire on the combustion fan. Any thoughts on why it may be doing this other than the control board being wonky? Not going to spend $400 on another one of the those if I can help it. Ignitor was replace in 2010 so it should be good for another year or two.
Also, the blower fan will come on during the first ignition and stay on through the second ignition on low. Then, it will go up to level 4, which is what I have it set on, and move on normally until thermostat temperature is reached.
