Dometic RM2310 rv refrigerator (1998) fails to light on Gas (propane),

Have had no prior problems with the RM2310, and it works OK on 12v.  But it will now not light-off on Gas.  I don't get a spark when I press the button which is supposed to light the refrigerator on Gas (propane).  

Is this hopefully repairable (preferably by a Dometic dealer)?  Could it be just a fuse problem?

        Thanks for your consideration of this problem,
