Ortur enclosure fan

When I select start the fan in my enclosure turns off and will not restart until burn is finished.
defeats the purpose of having the fan. is there any help to keep the fan running?

Do you have it connected to the controller?
If so, the logic seems reversed and if your relay is double throw, you can reverse it.

it works when I first turn on then if I try again it shuts off when I commence the cut
