Main vent fan in center of coach

[Pete Masterson]

My coach has a Fantastic Fan in the bathroom ... that works as
expected. It also has a vent fan located more or less above the
kitchen area in the forward section of the coach. This roof top vent
fan is controlled by the thermostat (when set to "cool") that also
controls the electric Perfectoe heater in the toe kick area under the
kitchen cabinets.

Through experimentation, I discovered that you set the thermostat to
"cool" and move the temperature setting toward the lower temperatures
to get the fan to cycle on. I also find that I can simply set the
"fan" switch from "auto" to "on" to get the fan to run. I can set
both switches -- heat/off/cool to cool (with the temperature setting
below the ambient temperature) and "auto/on" to on and the fan will run.

Now the question: No matter how the thermostat is set, the fan will
sometimes come on immediately when the switch is set appropriately
and sometimes will come on after a delay of some period of time (from
a few seconds to a few minutes). While the fan is running, sometimes
it will run continuously for a long period of time (that is, until I
turn it off) and sometimes it will shut down for 5 or 10 seconds ...
or a minute or two ... and start up again. During this start/stop/
start cycle, I've observed the thermostat with the cover off and
noted that the thermocouple in the thermostat does not 'flip' -- so
the on-off-on cycle _is_ _NOT_ being affected by the thermostat.

It is possible that there is a faulty circuit breaker that shuts off
power and then resets.

So, does anyone have any ideas about what is causing this behavior?
And, does anyone know where the circuit breaker that protects this
circuit might be hiding? (I presume that the fan operates on 12 volts
-- I haven't, yet, disassembled anything to start testing voltages,
etc.)

Any details or comments will be appreciated.

I'm thinking of simply replacing this fan with a Fantastic Fan (to
get the skylight effect as I have in the bathroom), so has anyone
done that? And, is it a good idea?

Pete-- I replaced my vent fan motor and switch, when I first got my
coach(motor was burnt out).I believe the switch has a thermostat
conected to it, up inside the unit. You could call them and ask, I did
hope this helps

Sound to me like the thermostat is bed.

Pete:
Mine operates in a similar fashion. My fan is 12v Kool Matic RV-12. With the
heat/cool side set to off, the fan operates when the auto/fan side is switched
to on. In auto and cool selected the fan operates if the thermostat lever is
moved below air temperature. In the on position it will run until it is turned
off. Presumably, in the auto position it will run until themperatures drop( I
am not certain) I was finalizing my side camera install today and tried it out.
It stayed on in the auto position the whole time I was working.
It does not run on heat/auto.
I have always used it with the heat/cool off and fan on. Didn't know it would
operate the other way until now.

Leroy,

Yes ... the Kool-matic fan. That's the one I'm talking about.
(Couldn't remember the name earlier.)

It sounds like the fan simply runs ... no starts and stops, right?
Mine will run for a while, then quits for a few seconds and then run
for awhile... I suspect a 12 v circuit breaker that's tripping then
resetting itself. The thermostat is _not_ the problem. I've switched
the fan on with the heat/off/cool set to off and the auto/on set to
on ... runs... stops... runs ... stops... runs. Same with heat/off/
cool set to cool (auto/on set to auto). Runs ... stops... runs...
stops... etc. ... I've had the cover off the thermostat and the
thermocouple (the coiled spring thing) does NOT move when the fan
cycles on/off (although I can get the thermostat to cycle the fan off
by moving the temperature setting above the ambient temperature).

I'm assuming a faulty circuit breaker, of course, the fan motor
itself may be drawing too much current, causing the breaker to
trip... either case, I can't put a tester on it (conveniently) with
out knowing which breaker and what value to be checking...

So, my question really is, where is the circuit breaker that services
the fan? I've got dozens of pages of wiring diagrams that often
provide little useful information (or information so encoded as to be
near-impossible to decode). So far, I've found description of many of
the fuses in the front compartment and those in the back closet ...
but many others of the fuses in both locations aren't described. The
descriptions up front are almost all related to vehicle functions...
but "house" functions aren't described. (Likewise the rear panel in
the back closet.)

<sigh> This is soooo frustrating sometimes.

Mine does not start and stop. It just runs until I shut it off. I could be a
weak breaker as you say or a loose wire, possibly at the fan. Unfortunately, I
do not know where the breaker resides. When I am up to the bus again this week I
will see if I can figure it out.
I did not check this. Since the thermostat that controls the fan also operates
the little toe heater, mine also near the driver, I wonder if that front A/C
master has anything to do with it. I had my front a/c on today while I was
working.
I do like the Kool Matic, it is a lot quieter than the bathroom Fantastic fan.

The AC switch doesn't see to affect the Kool-matic (but most
certainly does affect the toe-heater).
