Need help with MasterBuilt electric smoker

[SecondHandSmoker]

A and201 From the pics you posted, I observed what seems to be an excessive amount of rust on the back panel and other areas on the smoker.
That rust alone would stop me from removing the back panel.
In fact, the rust would make me think twice about even trying to repair the smoker or adding a PID controller.
If the rust is not stopped, it will continue to corrode both the internal and external sheetmetal. That is an undertaking I would not even consider.
And as tallbm mentioned, due to the age of the smoker, replacement parts may no longer be available.
This is just my 2¢ opinion.

Spent time today going thru wires and was able to fix errorF. Panel is back to work and with overheat switch bypass heater went on.
Great! Old boy will still smoke!
I will order new ceramic switch from above and hope will get it to work soon.

Many thanks to all who help with this thread!

Glad to hear!
Now you know a lot more about the wiring and the workings so if it craps out on you, there are some options for you to take :)
