Propane issue

A few days ago I had to break camp and drive the coach into Longmont for a Diesel Emissions Test required annually to renew the registration on the coach. When we got back I hooked up the bottle to the Extend-A- Stay like always. I turned the OPD valve very slowly like I have done very many times the past few years, gave the fitting a bubble bath, then turned off the main tank's sevice valve. As soon as I got inside the DW asked me why the refrigerator was beeping.
I checked it out and it would not run on LP. I checked the range top and the flame burned a few seconds then flamed out......

.....Is there any way to safely lubricate and/or manipulate any check valves or anything else? Otherwise, I'm about out of airspeed, altitude and ideas.

Never mind. I figured it out.[emoji848]

What was the solution, other than more airspeed?

It was a self-inflicted malfunction. The ACME nut was a little difficult (no, not cross-threaded) to turn all the way. I ran across a roll of yellow Teflon tape designed for gas connections in a hardware store. Why not sez me. I read about it frequently as being recommended.
The spool had instructions to wind at least 4 full turns on the male connector so...I followed the instructions like a good boy. I noticed that by doing so I couldn't quite screw it in as far as when there was no tape on it.
Long story short the tape prevented the tip of the ACME nut from quite reaching the excess flow ball bearing valve preventing gas from flowing. Bye bye yellow tape.

Excess Flow Device (spring loaded ball bearing ) is INSIDE the ACME Nut

Not being able to screw pigtail hose connection Fully into the Cylinder OPD was NOT pushing the OPD spring Loaded Check Valve Open

Excess Flow Device...ACME Nut/Pigtail Hose
OPD Spring Loaded Check Valve
2 separate safety features in 2 separate LP components

Oh great.....another valve to learn about. I confused the name with the ACME valve's name. Thanks O-B.
