The control panel is not a replaceable part. I had to buy a complete controller. Hopefully that takes care of things.
This was a used smoker so it's not under warrantee. Buyer beware. It was a Gen 2 model and only one month old, but the price was great. The people bought a product out of their comfort range. I was hoping that the new model would be free of problems but not so. It worked perfectly for almost a year. Coming from a Model 1, I was very happy with the digital performance and extra size, once I got used to it. The model 1 works great too. I donated it to one of my sons in laws and he's happy.
