The fan override switch lets you turn on the fan manually to keep it from
cutting in and cutting out as your water temperature hovers around 190F.
It's less annoying to let it run constantly than to hear it kick on and kick
off every few minutes. But there's another good reason to try it.

Just a brief story about my experience a few years ago in our 84FC-35.
Since we bought the unit in winter, the fan never came on during our first
few trips. I had never heard it, so I didn't realize it WASN'T working when
we needed it, badly, on Highway 16 winding through Custer National Park in
85-degree heat on the way up to see Mt. Rushmore that summer. We started
overheating. I added coolant and water at three stops until I finally ran
out. I had long since gone past any place where I could turn around. With
engine alarm buzzing and steam pouring out of the doghouse, I had to shut
down on the narrowest shoulder of a steep-grade switch-back and lost 30
hours because of a simple broken radiator fan wire.
Bottom line: Use the fan override switch to test your fan so you'll know
it's operational.
