Sorry for the long delay in getting back to the questions obout the regulator fix. I had to call the company a number of times to remedy this. First they wanted me to try turning the tank on 1/4 turn. Try that and call back. Next call a girl that told me 250 degrees was normal and that I should open the door to cool it down. Next call was to demand a new regulator as the first gentleman sugested, if the first step did not work. I had to fax the model # as well as the reciept to verify it was in warranty. Unfortunately, it took the 2+ months (on backorder) to send me a new regulator (front panel, hose, reg., and control knob assy). It turns out it was too small for my unit so I unscrewed the control knob assy. and replaced the defective assy. Now it works so much better. I have noticed that near the ends of my smokes, it is hard to maintain 225-235. It usually settles in at 240-250 (top vent wide open and knob as low as it will go). Awesome food none the less!
