RV Repair: heater wont come on, propane regulator, pilot light

Question
We have a 1987 Mallard Motor Home ,,, the furnace comes on, and blows, but never turns warm... we cant find a pilot light  or anykind of switch or anything, any suggestions ,, we are camping and its cold at night haha,, gas,,,, the water is electronic light , so guess this is too,,,, Donna

Answer
check propane level.  check propane regulator.  check gas lines for spiders...they love to lay eggs in propane lines.  check ventilation for plugs.  system needs to breath or flame won't light.  check igniter or thermal couple for problems.  look outside at ventilation to see if it is plugged.  then after all else, suspect the gas valve.  

good luck
