Hi there and welcome!
Amazon has a few sellers that are doing replacement
Masterbuilt smoker controllers but I didn't see one for your model and other parts places seem to be out. I don't trust
masterbuilt to actually get it for you either as their customer service is reported to be horrible.
The electronics and wire connectors are the weak point of the
masterbuilt electric smokers (MES) and the body is by far the strength, that part is rock solid.
So your options are limited but a very good option is to do the simple rewire (cut ends off 4 wires and wire nut to make 2 whole wires) and slap on a PID controller.
It would run you at least $150 to do this BUT you are now turning your MES into something that performs better than $1,000 electric smoker units out there.
I always say it's like turning a Golf Cart into a Ferrari and it will run 50x better then anything
masterbuilt makes brand new.
Additionally, if you replace the crappy spade connectors, and do this rewire job, you can keep this smoker running through anything short of it getting hit by a car :D
So really you are vastly improving something you loved to be something soooooooo much better and longer lasting. Beats buying another new one just for it to possibly have the same issues within 3months to 3 years.
I hope this info helpsThank you for the response. Would you by chance have a link to the exact part that i could use. I would very much like to keep and use the same unit. Also, Master Built customer service is extremely dissapointing to say the least. Appreciate the help!
