I just purchased a used Brinkmann Gourmet Electric Smoker. After a few days of using it to do test runs, I can not get the heat above 210 degrees.
At first, I had no lava rock in the bottom, so I filled the bottom of the smoker with it and tried again. (I read that covering the element with lava rock was ok. If it will damage it, please let me know!)
I fired it up again with the rock in, and still, the temp only got to 210. I read about some mods that you can do to the Brinkmann bullet to increase the heat, but they only seemed to apply to the charcoal model
