Yes, When under way, we check it at every stop to make sure its still running. We've found that on occasions strong crosswinds or perhaps a passing tuck has blown it out.
On my Dometic, there is a "CHECK" light. If this light is on, it means tha the flame went out, a couple attempts wee made to re-light, but they failed.
To reset this, I turn the frig of for a few seconds, then back on again.
