Isn't there some kind of thermocouple or thermister that has to be heated to open the gas valve. If so, it could be bad.
Not unless it is an older small cabinet type
Most use a Spark Electrode with high voltage spark to ignite propane flame
It would be HELPFUL if Brand/Model was included in post
RV propane system is only 0.4 psi so it doesn't take much to disrupt the propane flow and the propane/air ratio is critical for proper combustion
Burner slot(s) obstructed.....spider web, rust etc
Gas orifice clogged
Bad wire connections on spark electrode
Incorrect gap for spark electrode (1/8" - 3/16")
Loose/poor ground
Circuit board ------faulty circuit for gas valve
Typically a good cleaning of burner components will be all that is needed
