I have a Masterbuilt Pro smoker. My apologies on the lack of technical terms, but recently the Location just past the hose connector (where the one tube enters the other) catches fire. I'll come out to check on it and flames are shooting down from that area. I'm guessing the propane is catching fire at that point. It's not windy right now. When it did it a few minutes ago, I shut the gas off at the tank, then turned the smoker gas control off. Waited a few minutes, opened tank then set control to Low and hit igniter. It lit, but about 5 seconds later that area caught on fire again. Repeated process, but it's been 2 minutes and that spot has not lit up. What to do? This is the 3rs time this has happened. Last time I had to finish cooking in the oven because it kept catching on fire. Always on lowest setting. i can go talk to people at gas store but wanted to check here for any other solutions. Attached is pic of spot that lights up for reference, if my explanation didn't suffice. Thanks!
