Fans in the gen compartment

[Scott Forman]

On the ceiling of my generator compartment, I have two small squirrel-
cage fans that blow into a large rubber hose that exits under the bus.
I assume these are supposed to exhaust heat from the gen area, but does
anyone know what makes them run? Are they thermostat controlled? Best
I can tell, mine never run, and I am considering removing them to
facilitate some new sound deadening.

Anyone know anything about these?
