Dean, first of all welcome to the forum. Let's talk about the Bradley Digital temp readings. The temp sensor in the BDS in on the back wall of the tower(about the size of a nickel or quarter) and above the heating element. Dirty little secret of the BDS is the temp readings are not nearly as accuarate as an Auber PID until the meat load comes up to temp and then the temp swings disappear.
Now, as for those heating element failures. Bradley unintentionally and unfortunately wound up with some faulty heating elements. They acknowledged the problem and replaced everyone that went out.
Dean, enjoy the ride. We're here for you.
