I recently purchased the KC combo built a pad put it together myself then realized the frame to the smoker door was bent 3/4 of an inch. I called customer care they stated it was cosmetic. Door frame is structural not cosmetic. I just paid 800 for a bent door no no seal smoker. How can I regulate temperature? If the door doesn’t shut correctly someone please help me customer care, more or less told me to just deal with it.
