Shutting off the heat

[ronmarabito2002]

There are 4 valves on the engine. One is low behind the bumber. Shut them all
off. You will not hurt anything. That will stop your heat.

Jerry:

As far as I know the winter summer switch supplies 12 volt power to the chassis heat thermostat to run the blowers at each of the heat exchangers and the switch also should supply power to the 12 volt solenoid coils on the water valve or valves that have to open to allow the heated antifreeze to flow thru the chassis heat exchangers and thru the pilot/copilot heat exchangers. I am assuming that when you turn the switch to winter and the ignition is on it energizes the coils and they open the water vaves. If this is how it works then if the switch is off that would indicate that a water valve is stuck and not closing when the coil is in the de-energized state.

Do you have the front heat switch on the lower dash switched to off?

Wayne,

I have it set to summer but it still seems to poor the heat out. We are on I-5 heading back to Port Hueneme and it was a hot one today. My wife set a thermometer by her feet to check the temp - 105 degrees at the co-pilots seat feet!!! My feet were at 87 degrees. I had the generator running with two of the AC's going trying to cool it down. My dash AC doesn't work and I haven't fixed it yet. I was hoping there was some way to turn the heat off at the engine.

I don't think the heat of the generator and the heat of the road could produce 105 degrees in the passengers seat but I could be wrong.

Oh well, we will be home by noon tomorrow and I guess I can look into it further. Maybe I have a stuck valve somewhere that isn't allowing the winter/summer switch to work properly.

Hi Shane:

If the water valves controlled by the 12 volt solenoids are not dirty and working properly you just have to turn your switch's off and you shouldn't get any heated antifreeze to the heat exchangers. All it takes is a little debris in the water valve and the diaphram won't close off the valve. On my PT40 with the switch's off all the heat is off.

Hi Jerry,

Kelly and I had a good laugh this morning- at your expense of course- We couldn't figure ours out either and used to roast up front all summer. I finally realized that you have to shut off the 4 valves in the engine compartment to completely turn the heat off. Otherwise, the hot coolant seems to keep circulating- even with the summer/winter switch on summer and the front heat dash switch off. It sounds like others have clued you into this as well.

Thanks to all - good advice and very good info. I've made it home and will take
the time to look into solenoids because I don't believe they are working.

I just turned the water valves off this morning before I got underway - boy was
the ride more pleasant with the 105 degree heat!!

In my 94 pt the electric valve that closes the heat circulation path is normally
open. to close it requires 12 volts and consumes amp hours 24-7. What many call
a phantom load is simply that not realized. this valve was a phantom. One path
of engine coolant that can be kept functioning while the hear register path is
turned off is the water heater. that is why there are so many valves.

Hi Wayne,

Not sure what is up with mine- may have to check and see what (if any) crud is
in the sporlans. Funny thing with my dash heat is that when you turn it "on" and
the booster pump runs- it does not get warm. If you leave the switch off, the
pump does not run, but the dash heater core gets toasty. Had to run the heat
last night coming back from TX- this global warming has really cooled things off
here in the northeast LOL. The heater cores under the sofa and in the hallway
work as they should- it's just the front one that gives me fits.

Maybe it's an intermitent problem caused by a dirty sporlan water valve like you mentioned, or an intermitent electrical problem with the front heat switch on the dash or the electric solenoid that opens and close the water valve for your front heat exchangers.

I know what you mean about this so called global warming, we have been consistantly below normal temps. here in Mn. for 2 years now, it's June andwe still need a jacket much of the time.

hey there , the sporlan valees dont control the front heat, just the chassis
heat, so if the dash heat is still gettin hot, you can shut off the gate valves
at the engine, 2 for front heat and 2 for chassis heat,2 are hard to find, stuck
down between the frame across the back and the engine, but there should be a a
valve at the steering wheel, I was trying to think, they uses a pull cable with
a chrome knob by the steering column,to shut off a valve but not sure what
years, you pushed it of pulled it, then they went to a slide heater control,and
the valve was under the coach behind the step, and the had some problems with
it too, you could clamp off the hose with needle nose vise grips under there too

Shhhh! We're calling it "climate change" now, so it can mean anything.
Warm temperatures, cold temperatures, no temperatures, who knows! All
I know is, this "carbon" stuff is really dangerous and somebody needs
to be taxed!

... and here I thought the hole in the ozone layer was supposed to
have killed us all by now. Why does there always have to be a
boogeyman?

Oh, yeah. Forgot this is a Wanderlodge forum. Uh, clean the sporlans,
or something... ok? Great. ;-)

If there is no solenoid operated water valve for the front heat then what is the point of the front heat switch on the dash? Therehavea left and a right front heater blower switchs to turn either side to high/low or off
