HVAC Blower Motor Regulator Resister replacement.
The blower motor resistor is sometimes also known as a blower motor control unit, and its purpose is to regulate the speed of the blower fan. The electricity going into the resistor is often a constant value from the main power source, and the fan speed is controlled by the output of the resistor. Due to the amount of electricity being managed by the blower motor resistor, they can get quite hot during normal operation.
