I have a camp chef woodwind. Actually my second. My first flamed out and then caught fire. camp chef sent me a whole new grill. I am using traeger pellets, and I get wild temp swings 50 plus even up to 80 degrees. Camp chef sent me a new probe, and still seems like its fluctuating a lot. I put another email into them. I've had it for a year, and almost every long cook flames out. Temp swings start normal, then it gets out of whack, and flames out usually about 3-4 hours into the cook. The only good thing is the fire pot clean out allows for a quick restart once you dump all of the un burnt pellets. I usually watch the grill like a hawk, so i can catch it when it flames out, and keep going. hoping that camp chef can solve the problem. I had a traeger for a few years before the camp chef, worked fine for a few years, then got tied of problems with it not starting etc. Thinking of going back to traeger for the new 575 pro with the D2 drive. Love pellet grills when they work.
