This is the problem I'm having with my 182A

Works great until turned down at night. The only diff: mine is hard to
start after the next morning.

I too was thinking it was the thermocouple in the combustion chamber.

Try setting it to med after it's cooled down. If it goes out, I would
imagine it's the thermocouple, flame size, or possibly the size of
opening in jet.

I don't recall right now if the 182B has a different size jet than the
182A ( I think it does) but at higher altitudes the size of jet
orifice may have an effect.

There was a thread not long ago (less than a year ago?) that talked
about, in part, Dometic jet orifice size and altitude.
