Considering I live in Texas, I might also need it to run while being hit by a tornado :)
So, why will this make it better than anything I can buy less than $1000 and where do I start?
Also, yes, no power to the top controller which I replaced. How can I find out which pins carry voltage and what sort, I assume DC but what voltage and which is ground so I can see if power is actually getting there?
Hahaha well not sure how to tornado proof it, just gotta cross the fingers and hope it doesn't get hit :D
covered some of this in his post but I'll also elaborate on how the rewire and PID controller make the smoker amazingly better :)
The rewire and PID controller will make it to where your MES hits and holds right on or within 1-3 degrees of the smoking temperature you set it too. It will also be sure to ACTUALLY hit that temp.
The stock MES intentionally does temp swings to attempt to give you an average that is near your set temp. So if you set to 250F it would swing up to like 265F and drop to like 235F over and over. Also mine and many other's out there never actually hit the max 275F temp which sucks.
Why does hitting and holding on a temp matter?
It is precise, reliable, and repeatable. This matters when you attempt things like sausage, bacon, and jerky where you need tight control of the temps or else you can easily melt out all the fat and ruin the meat or simply overcook the meat.
Also if you want to smoke something hotter and faster you can actually hit that 275F max temp. A brisket, pork butt, or ribs do not care what temp you cook them at so cranking it up makes sense to speed up the cook.
How do you find out info on the pins and voltage?
You have to get into the circuit board on the bottom side of the smoker.
The circuit board will likely have the markings to tell you about the pins... if you are lucky.
Also when you look at the board you may see burnt out/busted/swollen/rusted components that let you know what likely went on.
If you know how to work circuit boards there is a chance you can repair it. There is little chance you can find a replacement board since it seems Masterbuilt
never seems to have replacements since the pandemic.
I'd bet money something is busted on the board and your only real option at that time is to do the simple rewire down there and to look into a PID controller.
Here is a detailed post with pictures on the rewire for using a PID controller.

Let me know if this all makes sense and don't worry, you can get this thing up and running no matter what without spending the money it could cost for a new smoker :)
