Switch Identity
I just purchased a 2006 Thor/Coachmen/Kodiak/Skamper 24RBSL. First let me say they are a little generous with the measurements (24RBSL is 22 ft of trailer, not 24 ft).
But to my question: there is a single switch on the wall next to the door that I don't know what it does. When I turn it on I can hear a 'humming' from, I think, over the refrigerator which is on the other side of the wall. Any ideas?
But the true travelers are they who leave for leaving’s sake
Saying continuously, without knowing why: ‘Let us go on’.

Does it sound like it may be fans. Perhaps they put a switch on the fans in the refrigerator bay.

Sounds like a motor but not a fan.

It is a switch for awning lights. If you look above the awning there is an out let to plug in the lights. That turns them on and off

Here’s what I know so far: (actually my DF told me), the switch is connected to a WFCO 3-Stage Converter.
This is what the book says:
‘The Parallax 7300 Series electronic power converter is designed to supply the nominal 12-volt filtered DC power to all 12-volt operated devices encountered in RV service.’
‘The 7300 electronic fan cooling system is the key to long life and trouble free operation. Fan is never on more than required to cool the electronic components of the converter.’
Neither paragraph refers to an on/off switch, but what I do know is, the fan doesn’t operate without this switch in the ‘on’ position. The question then is: Does it need to be on all the time when in use? Because the lights all work just fine, either way.
But the true travelers are they who leave for leaving’s sake

If you take a voltage reading with the switch on and off and the voltage is higher in the on position then the switch not only runs the fan but also the converter. The fan will cycle on and off depending on the load.

Interesting. My last two RVs were the opposite...had a 5th wheel, model 3400, it was 38' long, my current MH model is 40, it's 41' long. Go figure!

I learned also that the model numbers don't necessarily equate to the actual length. My Excel 33RSE is supposedly 34' 4" (according to the specs--I've never actually measured it).

thelastplace, I had the same convertor in an 05, if three 12v, lights/loads were on in the unit the fan wouldn't run , turn on a forth and away it went. Usually would cycle on/off on its own after a few mins. If the battery charger was working hard, after a couple of days booning, the fan would run until the charge rate cut back.
Does the switch look original to the unit , or is it possible someone added it to stop the noise; or hide the fact that the internal t'stat in the convertor is gone?

If you have a fuel station, it could be the emergency power cut off switch.

WFCO and Parallex are two different companies far as I knwo (Which I do admit is not far)
Why does the fan run only when the switch is on?
(Question, does it run when plugged into shore power)
Because it's a 12 volt fan and that is your master battery disconnect -OR-
If you bouht it used, because the owner einstalled the switch to override the fan's failed Thermostat controller.. Take your pick.

My rig is a 29WB which is 31 ft long. The model number has nothing to do with the size.
A friend told DMV that she has a 24 ft rig. It turned out to be Jeff Gorden's number (NASCAR)

I've been away for a while regarding this post and I appreciate all the replies. This is what I can tell you: the switch is (or looks) original: when it is on, the light under the step is on (when off/off): the TT is home, so it is always on shoreline because we use it as a 'guest house' so I don't know about the switch and no shoreline: because everything is working OK, the switch has remained in the 'off' position until further notice. Again, thank you for all your replies.
