I'm a new member from Southern California. Just bought a MES 40 model #20070311 for making Thanksgiving dinner. The MES with the round edged control panel on the top back, I believe its a Gen 1.
I've used it two times and each time, the smoker would randomly shuts down whenever adjustment on the control is made, such as changing the time setting, temperature setting, or when checking probe temperature. This happens when using both the control panel and using the RF remote control. When this happens, all the settings are reset to default setting of zero minutes and 100 degree F.
Sent email to Masterbuilt and they suggested I cut the cord and email them the picture and they'll send me a unit that may or may not be the same model that I have, depending on what's in stock. Since, I didn't want to take a chance on getting a 2nd gen MES, I'm hoping someone in here has come across a simple solution to the problem.
