Broke the knob off

So easy! Really, like changing a light bulb. I broke the timer knob off, so I would have to pull the knob out (to turn it on) with a pair of pliers. Once the part came, with the assistance of the pliers just turned the knob counter-clockwise and it came right off. Then just screwed in new knob. No more spring (like in the original one). It literally took about a minute to change.
