Greetings and salutations,

   After quite a few smokes on my XL, I had the same problem occur this morning that others here, like Petpoor and Barrycuda reported with their smokers. My smoker has been very good about coming up to temp, but this morning, I couldnt get it to go past 200. It was not too cold, 31 degrees and no wind. SO I looked at the flame, and it was pretty low. I played with the valve and it would not adjust the flame uniformly. It would go high and back down to a low setting. I pushed in on the valve while turning it a couple of times and the valve started working correctly with the flame adjusting higher or lower like it normally did.The temp shot up to 250 almost immediately! I backed it back down to the normal position to hold 225 and it has been working fine ever since.

I dont know if this will help others here having low temp problems, but it was something that never happened on mine before, which could possibly explain the reason others here are having temp problems. If this becomes a recurring problem, I hope Masterbuilt will stand behind their product and make a replacement valves or rebuild kits available.

Petpoor and Barrycuda, give this a try. Turn the valve back and forth while pushing in on it. See if that gets the valve working correctly.
I'm not familiar with your smoker, but I am familiar with Masterbuilt as a company, and there customer service is very good. So if your problem persists contact them and I'm sure they will resolve it.
31° does not seem cold, but if your tank is low, the gas pressure will be lower in low temps.

Would be my guess.

The tank was low, but I still got another 7 hours out of it before I had to change the tank. That was after the initial low temp problem was cured and the smoker was back up to temp. It was the pushing in and out on the valve while turning it that got it going again. It maybe an O-Ring sticking or cut that causes this problem. Im putting this accidental discovery out there for others here to check that have reported low temp problems.
