if it is the typical WFCO panel, and it won't stay latched it's probably the latch pin in the door. Those are avaiable as a replacement part, most any RV shop should have them, if not amazon or ebay probably has them. I had one break on our 2011 Outback and easily found the pin online, but don't recall where it was.
