I replaced my tv in the bedroom and discovered this fan after I removed the tv. Can anyone tell me what the fan is for and how does it turn on and off?

Muffin fan like those used in computers. It is for removing excess heat from the cabinet the tv was in. Did you purchase your motorhome new? It looks to me more like something a previous owner might have installed. The fan probably runs on 12 volts and is either controlled by a switch or a thermostat.

I bought it used. If it is controlled by a switch or thermostat where would they be located?

If controlled by a thermostat there would have to be a thermocouple somewhere in the cabinet. If controlled by a switch, your guess is as good as any. I'd try to follow the wires back as far as I could.

Looks like an add on to me...so if it's a switch you should be able to find it by running the wires...if it's a thermostat controlled fan the thermistor should be located near where the heat source was located...probably in that cabinet.

The small black item up higher on the wall with the gray wire attached may be the thermal switch, hard to tell.

The fan is an add-on attempt for the thermistor to actually sense air temperature in room vs temperature in cabinet. Room temp varies greatly from the set numbers on thermostat.

You may find the thermistor is in the fan itself?

Yep, that looks like a thermal switch. Looks like the white wire is the ground side and they broke the red (hot) side with the thermal switch. Better hope it's 12 volt due to the exposed hot leads

It is probably original equipment. I believe I can see the same fan through the louvers in the back of the TV in my bedroom. Not sure what starts and stops it, but Newmar will know if you call or ask via E-mail.

If its 120 volt it might knock you on your rump if you touch it. 12 volts won't . Look on the fan and see if it doesn't tell you what the voltage is, but I think with the black and red lead off of it I'm sure its 12 volts. You know, it isn't a bad setup.
The thermal switch should have a temp on it also. it should make on temp rise.
Was it a tube TV?

Are the louvers open to the weather with no covering. If that is so would a factory item be installed like that. looks like a DYI to me, or a very bad factory design.

Welcome Cathy & Paula to the Newmar forum.
As everyone has said it maybe a add on by someone before. You would have to trace wiring to its source.
A area above your drivers seat cabinet with the fan for over head cooling of windshield could be the source location.
If your in the process of installing a LCD tv you would not need the fan all you need to do is disconnect it. If its a fan in cabinet over the recliner you may need it for HI-FI amplifier and other equipment associated with it.
In the QUICK TIPS LINK below there are some installations by people on the forum that can give an idea for your installation.
Enjoy the forum and feel free to ask as many questions you need.
Thanks for your service and survivors as my wife is also.
