Shutting off the heat

[Wayne Kotila]

The sporlan valve is opened by a solenoid which is just an electro magnet that when energizedcreates amagnetic force that opens the water valve. The switch on the dash is a 2 wire switch and you can swap the wires around and the function of the switch does not change, it just makes or breaks the circuit. You cannot wire a 2 wire switch backwards, the only thing you could do backwards on the switch isput it into the slot on the dash facing the wrong direction so that when you have the rocker switch pushed to the off position it's really on and when you have it pushed to the on position it's really off. That is a very likely possibility of the problem, the other good possibility is the sporlan valve is stuck open, all it takes is a small amount of contaminants in the valves
diaphragm to cause it to not open or close properly.

Hi Tim,

Sadly, ye be mistaken. There's a sporlan behind the air step mechanism under the front steps that opens (or is supposed to) when you turn on the front heat. I can hear mine click when you rock the front heat switch- my suspicion is that it's wired backwards and is closing when it should be opening- so when my pump is on, the sporlan is closed- but when the pump is off- it's open. I'm willing to bet that it has been like that since the coach was built. We're going to troubleshoot it at the WarnerRama rally in New York later this month.

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
