My '86 C-36 has a CNG oven and stove from GSI, which I believe is original. On a recent two week cruise, the oven suddenly became inoperative. We could light the pilot light, but not the main burner in the oven. Has anyone experienced this problem before? Can the gas line be unclogged as a DIY project or is it better to take it to a professional? Thanks for the help. Les Murray s/v Ceilidh '86 C-36 TRFK
