Another ,,What is that thing for? Question

[Paintblend]

On my 1996 Mt Aire gasser 460 ford,, in the cabinet below the refrigerator, there is a quick disconnect propane gas valve,,, with a shut off,,, my question is what is it for and why is it there,, and one more question is my dash ac works great,, too good,, the compressor will not shut off and runs as long as the engine is running and it will freeze up the coils,, even if the ac is turned off the compressor still runs,, it does not cycle ,, like it has power all the time once the engine is started,, i have to unplug the compressor to make it stop

thanks in advance

What the quick disconnect is for I can't say.

As for the air conditioner.. The clutch is siezed and needs to be replaced by someone who knows how to do it.. Either that or there is a short.

now, to check whitch.. There should be one, and only one, wire to the compressor, just behind the pully is where it connects.. Disconnect, tag and tape. If still runs, the clutch bearing is siezed and will need replacement.

when i unplug it the clutch will stop so i need to check for a short

I will take a guess on the LPG QD and Shut-off valve, it may have been installed for a LPG space heater or some other LPG device that can be hooked up to the QD. Is that area accessible from the outside? if so, it could have been used to connect up a LPG BBQ grill.

Regarding the A/C, you have some very reasonable explanations and I am by far not an A/C expert.

just a thought, check your heat control selector. if in defrost mode the compressor may run to dehumidify

the compressor runs no matter where you have any of the controls,, when you turn the ignition key on you can hear the clutch on the compressor kick in,, i have thought about just wiring an inline toggle switch just to cut it off before it freezes up the coils or the evaporator,, when it stops raining i will try to trace down the wires from the compressor and make sure there is not a short ,, i am just not that familiar with the relays and other electrical connections with it,,, and on the gas quick disconnect i never though about a heater,, and i already have an ouside connection to my grill from the main propane tank,, it works great, no more little green overpriced propane containers,,

A/C Clutch Relay is prolly stuck.. Just where that is on your coach, I have no idea. It should be a generic Bosch 30amp relay though...
