Use chips in your favorite flavor,
Cold Plate with lots of ice in pans on lowest rack.
Cheese on top rack.
Crank heat with door open, turn down to 100 after good smoke is viable.
Leave door open to release any built up heat.
Close door, after 30 minutes open door, flip cheese, checking for excess heat and melting.
Continue to smoke and check, as you feel necessary.
Do not crank the heat with the door closed, do not seal the top vent hole.
