Vent fan(s) malfunction

[DHeb51]

I have a 2007 Revolution LE. Will low batteries or if one of the four batteries is bad, will the vent fans not work properly. During such time I noticed fans were not coming on or going off from the switch. Problem 2 is in the process of pulling down the controls to go to manual I broke the control. I do not have any manual on the vent fan and do not know the name of the fan (or at least cannot find a name). Can anyone help in this matter(s). I since have replaced all of the batteries but have not tried any of the other fans to see if they are working properly.

If you are talking about ceiling vent fans chances are they are made by Fan-Tastic Vent Corp. The contact info I have for them is 1-800-521-0298 and www.fantasticvent.com. They may be able to help you.

If you batteries are bad and Rv is not plugged in, than nothing should work. It's good you replaced all batteries not just the bad one.
