Recently run into an issue with my Castle Serenity pellet stove model 41278. I installed it this fall and it has ran flawlessly until now. During lighting the auger will run normally until almost fully lit, at that point it will start to short cycle (run about 1/4 of the time it should), and the stove will fault with a failure to light. The wife told me this happened a couple of times while I was at work. I have emptied the hopper of almost all pellets, ran diagnostic on the auger and it runs with no problems in diag, pellets flow with no issue into the firebox when manually running the auger. I am now wondering if there is a program issue and if so how to fix it. Stove has 261 running hours on it
