I called Masterbuilt customer service today and asked how much the digital "brain" temp and time controller costs to replace. I was told 39.00. That to me is a good deal that I am happy with. She also told me that if you keep your original receipt they will honor warrantee problems for up to 1 year. I questioned that because the warrantee states 90 days. She said in most cases if it is a product failure not caused by the customer, they will honor 1 year. They have the greatest customer service I have seen in todays market. Ya know a person in India that don't speak'ed english, or very well? Anyway I hopes helps the owner's and possibly new owners of the MES. I love mine, good luck and good smokes!!
