I bet this is your problem. Turn it on the full tank and see if will run now. If it does then extreme cold was probably it.

I though I remember this being an issue with someone else with the cold weather.

Thinking to swap out the 6500 Commercial 220V for a Diesel. Propane too thirsty and not pleased that it would ice up and stop running.

LP tank probably "froze". Constant negative pressure running a tank in cold weather it will freeze up.

I read placing the LP tank upside down will not freeze up.

I also watched a video, the guy changed a LP 5500 Onan to gas. Looked easy.

Then I would need to install some sort of fuel tank.

Turning the tank upside down means you are drawing off liquid propane rather than propane vapor. Good luck with running appliances on that.

A I had a Safari DP with Onan propane generator, 6200w on LP,
The 100# frame mounted tanks are set up for liquid delivery, the vaporizer? Is mounted at the generator intake manifold, where the carburetor would have been,
AFAIK LP from 30# cylinders is strictly vapor feed Not LIQUID,
A pressure regulator at the cylinders can Ice Up, from the moisture in the tanks freezing due to the COLD outside ambient temperature and the cold produced by the vaporizing of the LP, the lower the LP volume, the more likely this will happen
Also sometimes in southern states in warmer weather you get LP that is more butane than propane,should not be the problem if you filled the cylinders recently, but if it's been a few months, like summer or early fall? Who knows?
butane will not turn from liquid to vapor at 13°F, as temperature drops below 32°F, the process slows down until it reaches the point where it stops, the generator simply gets no fuel or not enough fuel to stay running, neither will the heater etc..and the regulator does not have to be iced up (frozen), there is simply no fuel vapor to burn


I can explain it to you.
But I Can Not understand it for you !

That tank had been filled in DFW, TX a week before.

So basically propane is not the best setup if in cold weather! Not in cold weather much but if I am I sure want my equipment to work!

I will be looking into what I need for changing over my 6500 to Gas.
