"Flame sensor" is technically known as "the thermocouple." And thermocouples are widely known to need replacement from time to time. What usually happens when one goes bad is the ignition system will light up the burner but shut it off after a few seconds.
The thermocouple is a safety device, intended to insure that should the fire go out, you don't keep dumping propane on it, possibly leading to an explosion or somebody getting gas poisoning. They are cheap and fairly easy to replace, if indeed that is the problem.
Yes thermocouples are flame sensors but not all flame senors are thermocoples.
Thermocouples are 'old school' and not used in modern rv furnaces, fridges, water heaters....appliances that use electronic ignition sources
Spark electrode not only provides the 'Spark' for ignition but also provides the means for flame sensing. 'Flame Ionization'....no thermocouple used.
OP.......
Have your RV battery load tested
And then with a fully charged good battery turn on ALL propane appliances at same time. LP Regulator should be capable of supplying 100% of demand
Fridge (low demand---2200btu), water heater (med-low demand 10,000-12,000btu) stove top burners (med demand---19,000btu) furnace (high demand 30,000 btu)
Or using a manometer check propane system pressure (11" WC------which is 0.4 psi)
