sometimes works sometimes not.
If I where you I would disconnect the rod from the actuator so you have heat.
But here is a little test to make for sure your actuator is broken. With the arm/rod still attached to the actuator, try moving the arm of the actuator right to left..with the rod still attached. If it moves freely than yes your air mix actuator has a broken gear and does need replacing.
If you cannot move the arm than something else failed.
