every seanson, it seems, my stove squeaks when my augar is activated. It happens at the end of the season usually. I solve it by removing all my pellets and vac out my slide plate and puff in some powder graphite, as well as scrape me burn pot. That usually does the trick.I always blamed bad pellets with lots of fines for the squeal, however this year I'm burning green bag energex, I find these pellets to be good with low fine levels.My squeal is back and comes back quickly after my slide plate has been cleaned out.Does anyone have a reason this happens? If so is there anything else I should do to solve this? It's driving me crazy! I bought my Harman because I was told that it could burn anything and that may be true but it seems it cant even handle pricey pellets without squealing, seems a bit nuts.
