I finally heard back from masterbuilt. They will not support repairs on my unit because of the use of the pellets. Just an FYI!
That sucks. Looks like it is time to take matters into your own hands :)
Borrow or buy Multimeter
With the Multimeter (MM) you can test if the heating element is busted or not.
Also you can check for continuity along a wire. You just inplug both ends of the wire, put the MM on the continuity setting and if it beeps then there are no breaks or between both ends of the wire.
If it does not peep then you either have some breaks somewhere between the ends of the wire OR the two ends you are testing aren't actually part of the same wire. Continuity checking is super easy and very helpful when figuring out where something is going wrong.
Finally once you find the issue (busted connector, disconnected wire, ground wire issues, frayed wire touching something it shouldn't be touching, etc. etc.) you can then fix it.
If the wiring all checks out (continuity says so, and grounding is good) the issue is Masterbuilt components. In that case I suggest you rewire and go with an Auber PID controller and make your MES better performing than what Masterbuilt does :)
I did the same with my dremel and covered the hole with a piece of like 5mm thick scrap aluminum a buddy of mine had lying around. I used self tapping sheet metal screwed to fasten the scrap aluminum square over the hole and made my own panel. I then just foil taped over the edges to seal it from any potential liquid getting in.Yup. I cut out a square area on the back with a dremel cut off wheel to access the roll out switch when it fails so I can bypass it with a wire nut while waiting for a new one arrive. Everything looks perfect connection wise so I'll wait till something happens before changing to high heat lugs on that switch. The foil tape works great. I feel better now that I can quickly access componets in the Gen 1 40 that can fail without finishing in my kitchen oven.
I've had to open it at least 2 times as I learned that I was causing my replacement rollout limit switches to burn up since I was handling them too roughly and causing the tabs to loosen and wiggle which = electrical resistance = heat = melding my switches hahaha.
