The friction surface of a vented rotor consists of two metal discs held together with vanes of metal which creates tunnels that let the heat escape. We call those cooling vanes. With the solid rotor, the friction surface consists of only one metal disc. This greatly reduces its ability for cooling. It is a common misunderstanding that you can choose whether you get a solid or vented rotor, this is NOT true.
The Correct Fix. The vent door actuator is the electric motor that moves the door in your heating and air conditioning system to direct the air out of the different vents. These parts wear out over time because they are used so often.
