INVERTER FAN RUNNING CONTINUOUSLY
-
On mine there was no fuse or breaker for the bay fans and they are 120v.

Tom: “On mine there was no fuse or breaker for the bay fans and they are 120v.”
So the fans are “hot wired” to a power source without any protection for the circuit?
-
Tom is correct. On my 97 my bay fans were powered directly from the 120V output from the inverters with no circuit protection. I have not looked at my 06 to see if it is the same.

My fan is also wired direct to the 110V with no fuse or protection. The reason I know this is I installed a thermostat with it “hot” I knew I would not touch the wires together…. an ole pro like me..surely not. Then a blue flash. I knew I blew a fuse that would take most of a year to find. But it was still hot… installed a thermostat and set it to 80deg and my fan runs amost all the time..

Yep, mystery solved. Both the port and starboard battery bay fans are now operational. Traced the 1st fan cable on the inverter side directly into the access panel of inverter #1. As stated by many, it is hard wired diretly to the same wire nuts connecting the 120vac output of the inverter. Liberty conveniently added a wire tag labeling the cable FAN. About a 16 ga cable with no fuse protection directly to the external fan. Runs continiously when the inverters are providing power.
Still no trace of the wire feeding the 2nd fan located behind the bay frig on the opposite side in the entertainment center bay. Before repairing the severed cable I flipped several 120vac circuit breakers to determine what else could be supplying power. Turns out the bay frig power is the same breaker that supplies the primary coach frig. It also provides the power to the 2nd fan regardless if the bay frig is on or off. Essentialy both fans will run continiously when the coach is in use.
3 nights of crawling around in the coach bays is excellent physical therapy. Some people actually pay for a work out like that!
Thank you for all of your input.

I believe the second fan you mention is the fan for the entertainment center refrigerator. It draws air from beneath that refrigerator and exhausts it into the open area at the batteries and the aux compressor. That fan is thermostatically operated at the small refrigerator so when it cycles on the fan comes on.
