A few years ago I bought a small (~3' hi x ~1.5'wide x ~ 2' deep) Masterbuilt electric smoker, after years of using a classic New Braunfels. I loved it, but after maybe 2 years, it just stopped working. I called the company, and they told me if I could prove I'd bought it in the previous 2 years, they'd send me a new one, or if it had been 3 yrs, I could get a new one for half price. I had no idea where any receipt was, so I was out of luck. I got the impression the problem was in the digital electronic controller. Does anyone know if there's any way I can fix this thing, or do anything useful with it?
