The controller and probes are warranted for only 1 year. I personally think that is fair. IF CS manufactured the components, then I would expect a 2 or 3 year warranty from them. But since they source the controller and probe, they can only warranty the item for what the OEM warrants it for. It is like that with a lot of companies. Not all but a lot. CS makes a great smoker and for anyone who wants something other than one of the competing look-a-likes, that is Made in the USA I will recommend CS.
