I called in and asked about the control module, but said they'll only send me a new high temp sensor first and see if that resolves it. The rep was nice to deal with, although did say that it was unlikely the element would still be on at 403 degrees, so my probe may be off. When I asked why it'd be on at 310 (like the smoker showed) she then offered the sensor.
Fingers crossed that this solves it and I won't need to call back and get a control module sent too.
