It's a Norcold 682 I'M found drawings no thermocouple

Brett, Cleaned burner , orifice and igniter , have a better flame but still goes out after 10 sec. There's some interlock that tells the unit to turn off. I don't see a thermocouple , unit works fine on A.C.

I looked in the burner but didn't see any thermocouple

Pilot lights but then goes out about ten sec. later Is there a thermocouple that needs heated to open main line ....
