So are there any suggestions on what I need to do? Replace the burner? Restrict the burner in some way??
Thanks in advance!
If you leave the smoker cabinet door cracked it will allow more heat to escape.
It's kind of a crummy way to get the temp down, but other than adding another exhaust vent on the top I don't have an answer for you.
Hopefully someone with your smoker will come on & give you a better answer.
I also had that problem with my Char Broiler smoker. You can add an in-line needle valve to get down to lower temps. You can find them online fairly easily. I put mine between the regulator and the control knob on the smoker. Once you set the smoker to the lowest setting on the control knob you can further lower the flame by playing with the needle valve.
