Also, note that it's the condensation on the cool interior surfaces, after shutting the fridge off, that causes odor. Once the doors are wide open long enough to equalize inside surface temperature with room air, the now dry fridge can be all closed up to keep bugs and dust out, without fear of mildew and food decay odor.
It that light, it is better to prop the door open only temporarily and never store it open for extended periods.
