Having a problem I have not seen before.Turned it to propane,preparing to head south.Burner would not lite it tried but would flame out around tube.Found usual bug nest and cleaned it out.Turned it back on nothing would happen did not try to lite.After checking fuses and voltage seamd to be OK but could not get reading at gas valve.Ran test from owners manual and all checked OK.Gas lit on last test and flame was recognized.Closed test and it would still not switch to propane.Waited awhile tried again and it worked.It is on propane setting not auto.Anyone have a similar experience?Thoughts?Unlike some this is first issue I have had with it.Thanks
