Yes. The wheel that sets the temperature has a strip of tape that wraps around the circumferance of the wheel. The tapes come in celcius and farenheit. Maybe your farenheit tape fell off or was removed thus exposing the underlying celcius tape.

Just a guess.

You can get a new farenheit tape from the dealer... possibly even fastlane.
