Mr. Resistor is a "resistor", he sorta resists/ restricts electricity. When the juice is restricted something starts building up heat, that would be resistance wire of the resistor (kinda like an electric stove eye).
Most blower motor resistors sorta permanently poke their head into the duct work of the HVAC unit. Reason being, when the blower fan is turned on it's air is blowing over it. Not only does it keep it cooler, it also prolongs the life of the resistance wires.
Smoke would be normal if it were not installed.
In an emergency situation, MacGyver could snatch it out to start a fire, or simply light up a menthol during a nicotine fit!
