Ok how gas works
Thermisistor inside cold box gets feelin a tad warm and changes it's resistance
Control board senses this and thinks "Guess it's time to heat the boiler up" (NOTE this part is working cause it works on electric) so let's start watching her.
It opens the gas valve and starts the Direct Spark Generator.. you should hear the "CLICK" of the solenoid and the "SNAP SNAP" of the ignightor if you do not you have suspects.. IF you hear the CLICK but no snap the solenoid valve is LIKELY good (not guaranteed) if you do not hear the click measure voltage on the solenoid (Should be near battery voltage) if none control board or connection bad.
If valve working (You may be able to detect the gas smell/flow) And no SNAP look at the ignition point spacing. Compare to what the owners manual states it should be.. NOT on a fridge but I've worked on two furnaces. one house one RV with DSI both had wide spacing. Resetting made a 100% improvement.
Now if you have gas flow and spark you SHOULD have flame Look at it you may need to adjust air/fuel mix a bit... If no or poor flame the gas jet (orifice) may need attantion (Cleaning). Or there may be a supply side issue (You topped off the tank,,, Did you or the technician remember to open the valve when done?)
Now the flame heats the thermocouple (this is different from a thermistor) and it starts to generate voltage/current (Not much of eaither but enough) the control board senses this and continues gas flow till the Thermisistor inside the cold box starts feelign "Chilly" once again. at which time it shuts down.
Possible issues
No flame: Spark: Bad control bad connection Spark gap too big
No flame: No gas flow, bad vavle, tank off, other obstruction, clogged gas jet
Flame but shuts off swiftly. Thermocouple dirty... bad bad control board or connection
OVERHEAT... flu needs cleaning
That is about all I can think of but I'm sure I've missed some stuff.
Home was where I park it. but alas the.

Check the flame chamber for rust flakes. Doesn't take much for the control board to shut the propane off. Your vintage of coach could have significant rust. Vacuum or blow out then give it a try. Good luck, Don

I am glad you noticed my limited grasp of the English language. I do as well as I can considering my 8th grade education. As awful as it sounds it’s all I ever got. Hope I helped the OP

Sarcasm noted.
Not sure where you're living, but in the US, education is free up to grade 12, if you choose to avail yourself of it, such as it is these days, graduating mostly functional illiterates.

Well at 81 I had very few choices as a youngster in Appalachia. No indoor plumbing, outhouse, wood stove for both heat and cooking, farmed with horses, no car, no phone, no electric, no TV, kerosene lamps for light, hunted or raised all we had to eat. We had nothing so at the ripe old age of 15 after not going to school for 2 years I walked out of there and have done pretty well since. But there will always be those holier than thou folks that will look down their nose at me because I miss spell a word now and then. So be it. I'll still help with your refrigerator if I can, no problem.
