1. How do I check if I need to add more wood chips or pellets if the door shouldn't be opened during smoking, or is it ok to open the door for stuff like that? 2. Is it true Masterbuilt will send me a larger wood chip tray for my MES 30 if I ask for one? I washed the door interior with soapy water, forgetting that only a damp cloth is to be used. I presasoned my smoker last night. Do I have to do it again?
