My st croix Hastings has been nothing shy of problematic since I installed it. I replaced the board right after Christmas. Set the settings for 3 (which my manual says is what I want for pellets) and it ran great. No black soot. Nice fire. Full deep clean from removing fan, to emptying pots and traps daily. I had unplugged the stove from the wall to clean a few things and plugged it back in from use. My question is does the board only get programmed one time? I assume after power loss of any sort would need to be reprogrammed. But when I try it (cold I know) it doesn't do anything but blink 5 times. It's now starting to back up pellets up into the feeding tray and not fully burning them. Since this has started, I've a few times taken everything out including bricks, ash traps. Vaccumd every crevice. I've even had blower off to really get in there.
