RV Repair: refrig, burner tube, gas valve

Question
my rfrig works on elec but the prophane side wont light i hear it clicking

Answer
Bill,
    It sounds like you may have a gas problem since both your frig and furnace are not lighting.  Do the stove and water heater light okay.  If so you probably have a dirty burner tube on the frig.  If cleaning that and setting the gap on the ignitor doesn't solve the problem then it too is probably the gas valve or circuit board.  I hope this helps.
