Hello, is there anyone that can help me out? We bought a brand new King Pellet Stove model 5502. We have used it a hand full of times to stay warm this past winter, we cleaned it before we stopped use this spring and made sure to have it still in new condition before this fall. However, my husband and I tried to use it tonight and have run into a problem. On the automatic settings, like we used last year, it will turn on like normal and start burning a fire and heating up. The problem is that when it heats up it doesn't then blow out any of the air, it instead just keeps heating up and cracking and expanding. Then when we shut it down, it begins to start blowing out the warm air. Very confused as to what's going on with it! Any one have any answers? It's still pretty much brand new so there shouldn't be any reason for problems yet!
