So I have been smoking for a while using an offset rig, with good success but recently had an addition to the family, so finding time to do a good 6 - 18 hour smoke is a little bit more challenging. To help I figured I would try a Electric smoker for things like Brisket, ribs and smoked pot roast.. I picked up the Masterbuilt 30" Analog off Amazon this past week for $99 during a flash sale. Cleaned it, assembled and seasoned it before my first attempt. The problems: 1) Wild Temperature swing, I turn it on High to clean it, came out and found the temperature spiked, using a laser probe it registered 500 degrees, which seems very high for this kind of rig. Later on a "medium high" hit 220'ish which seemed more like the target spot. Later "low" was around 220, and the previous dial setting went up to the 380 range. 2) Wood chips would not burn, just smoldered and smelled fairly terrible. I do have it assembled properly (appears to be a common problem), was not using large chunks and had the water pan in. Chips were dry, not soaked as seems to be suggested. 3) No adjustable air vent, I see lots of talk about one, but only see a small 1" whole on the top right rear. Thoughts? Suggestions?
