Hi folks, I'm new to smokers and was recently gifted a Masterbuilt Pro dual smoker. I seasoned the smoker this morning for just under an hour and was able to get the heat up to 400 deg during the seasoning time. I then proceeded to start up a pork butt in the smoker and for the life of me I can't get the heat to go above 200 deg. I notice that when I adjust the control knob that there's a brief flare up but it quickly goes back down to its steady burn. This is case whether I have it at max or min. Working with the equipment is new to me. I don't know the in's and out's of working with the heat system other than what the manual provided. What else in terms of troubleshooting can I investigate as to why I can't get better heat control before I call up Masterbuilt and troubleshoot with them directly? Thanks in advance. [Solved] Not sure if it's a permanent resolution but I simply turned everything off and re-sparked the burner. After doing so I had better control over the fuel supply and easily got it heated past 200 deg.
