Easy knob to fit onto the metal turn rod
It is not the same design as the other knob on the Whirlpool AC, but works fine. It does seem about 10-100 times more expensive (~$40) than seems reasonable, since it likely only costs 40cents to manufacture. However, the bright side, it works!

Perfect fit
Just what I needed. I guessed because I didn't know the model number of the AC unit. When they pictures are like a thousand words it's true because I based this purchase solely on the picture under Whirlpool parts.

Sorry, we couldn't find any existing installation instruction that matched.
The cooling selector switch stopped working
First removed the power and front panel. Then in order to get to the damaged cooling selector switch, I needed to first drill out three riviets holding the small front pannel that the switch and thermostat selector switches are mounted on.

Then it was a simple matter to unscrew two small screws holding the broken cooling selector switch in place.

At this point, I unhooked each wire (about 7 of them) from their terminal connector on the back of the switch, and reapplied each to the new switch. After I was done I then mounted the new switch with the two screws and realigned the pannel.

The only thing remaining was to install the small pannel using three pop rivets and slide on a new knob, and reinstall the large A/C front cover.

FYI, The new replacement switch and knob were perfectly identical, and worked like a charm.
