I have a regular stock dometic fridge. After last couple of trips we have been battling mold invasion. WE have sprayed/cleaned and just cant seem to be rid of it. It seems that we need to remove the back portion of it - if the door is open, and you are looking in, its the piece that carries the metal "gills" in the back But we can't figure out how to remove it. WE would greatly appreciate advise on how to win this battle, we are going out this weekend and I can't use the fridge like this. Thank you!
