Gas cooktop won’t stay lit

Gas cooktop will light, but will not stay lit.

A little more information about your rig and stovetop would help.

That said.... have you bled the lines and how much propane do you have in the tank?

[Ross6250]

Class C with Suburban cooktop oven,Tank is full. Not sure how to bleed the lines

When the flame goes out is there still flow coming out of the burner?
If so just keep relighting it for a few times to purge the lines of air.

Have lite them 20 times or more
