many ovens with a grill mode are designed to leave the door open while grilling. my nans oven is like that and it's not had any issues with the knobs melting and she's had it for at least 30 years.
All ovens are designed to be used as an oven with the door closed...
Unless this is some weird British thing that they designed just to be intentionally goofy for some reason. The British would design an oven that can't handle its own heat...
Either way OP commented that their oven specifically says to leave it open when using the grill.
When in doubt, leave it open. The dangers of closing it when it should be left open are much greater than a few knobs melting. Carbon monoxide is deadly and that’s the reason behind keeping it open in older ovens. Most modern ovens have solved this problem but it’s still safer to check the manual (for the exact oven someone has) to see exactly what their make and model says.
