MasterBuilt 40" - Flame at Venturi Tube

Discussion in 'Propane Smokers' started by duke smoker, Nov 1, 2014.

  1. I have a MasterBuilt 40" propane smoker.  It is approximately 3 yrs old.  It just started flaming where the propane tube enters the venturi tube on the bottom front center.  I assume I have a propane leak there somewhere.  Is there a fix for this?  Or is it time for a new smoker?

    take the burner off the smoker and cleane it.i bet you have spider webs just happened to me
  3. Had the same thing happen to my masterbuilt xl40 last weekend along with very "lazy" yellow/orange flame, saw edgars post and went out and took my burner apart and sure enough, spiders and webs up near the bend in the tube. Cleaned it out and reassembled, works good as new.
