I have had nothing but good to say about Masterbuild and their service has been great. Lately I have replaced the control unit and heat element. The control unit comes on, the remote doesn't work and I have no heat. I have sent three e-mails asking for some tech advice, but have no response and they are taking no calls and I have no idea where to go or if it's just time for a new smoker??? Smoker is about 5 years old.
