Luckily our fridge has a cover in front that comes off to get to the coils.Happy belated B-day clue. Same question as @Peep_Show - Anyone but DH even remember it was your birthday?
IF you can get to them. The way ours is designed it is physically impossible to get anything off the coils that is more than about 2" in. All they would have to do is rotate the coils/supports 90° so the "Vs" would be accessible from their open side from the front of the refrigerator. There is no way to get to them from the side shy of jacking it up several inches. Really bad design .... or great design if they want the machine to fail early for more replacement sales.
Lucky since I did not look for this access when I bought the fridge!
