Yep, mine went out one fine weekend morning. Right when I was going to smoke a slab of cured Pork Belly for some buckboard bacon. Turned on the box, set the temps.. then nothing.. Nada.. Well, Masterbuilt was pretty good about it. They sent me a replacement heating element soon as it arrived from China free of charge including free shipping. Last thing was to install it correctly and not ruin a $400 investment.. Went online and found a great video on how to do this right. Its really easy. All you need is a Drill, phillips head bit and a 9/32" socket. If you're lucky, its only the heating element but in my case, it was corrosion on the heating element AND the wire connecting it to the controller. Great... Considering I baby this thing with a cover when not in use and a few mild winters, I don't know how this could have corroded after 3 years so quickly but it is what it is..No time to bitch about it. Just time to fix it.. Use the Yellow sized spade connectors. .25" with the appropiate crimper. here's the video... Really easy fix folks. You could actually upgrade the connections to the heating elements. I used shrink tubing over the lead to the spade connector as reinforcement. From the factory, they used some cumbersome rubbery covering that looked like a hot mess. I removed that as I am a tech by profession and hate ugly installs by nature. Once I put everything back together, the unit came up to temp quick as new. Smoked my pork belly without a problem. Actually, I was surprised by the amount of smoke it put in the meat by the time the IT reached 150F. I'm not going to say make sure the unit is unplugged because if I have to, you have no business doing this repair in the first place.. Smoke On!
