I may be mistaken, but I recall from other motorhomes that these fans have bi-directional switches. I may be that an incorrect switch was installed. I would photo mine, but it is too hard to get to.

Thanx you Chester but this particular switch is just off/on. The only difference between the original switch and the new switch is that the new one has an LED light when the switch is in the "on" position.
