Hi all. I have a St Croix Hastings and it has been basically trouble free since 2008. Come home today and stove is not running and number 2 light is blinking... leads me to believe vac switch is bad. I jumped out the vac switch and when I turn the power on the auger feeds, but the exhaust fan does not turn on! If I disconnect the jumper, and power it up with no vac switch connected, exhaust fan runs like normal but after 20secs it shuts down and gets number 2 error.. jumped out hi limit switch, pof switch and still the same problem. Any ideas guys? Still cold here in Ny... thanks.
