Reply to "JLC Big Boy smoke unit"

I suspect the regulator module.  With this smoke unit model, the heater voltage doesn't power the fan, the smoke unit gets 3rd rail direct to power that logic chip that controls the fan.  The smoke heater is powered directly from this module, which is almost surely bad.
