When your refrigerator does not cool properly, has a light layer of frost along the back wall or door of the freezer compartment or a buildup of ice in the freezer, you will need to access the evaporator coils to fix it. The evaporator coils sit in the back of the freezer compartment of a refrigerator and look like a radiator. The back wall of the freezer is actually the cover of the evaporator coil and can easily be opened with a screwdriver.
Empty out your freezer and place the food items in a cooler with a lid.
Unplug your refrigerator. Remove any frost or ice buildup by running a hair dryer on high heat. Mop up the melted ice with a towel.
Remove the icemaker mounting bracket screws (if your refrigerator has an icemaker) with a screwdriver.
Remove the evaporator fan duct screws with a screwdriver. Pull the tabs located on the evaporator fan duct down to unlock them and pull off the evaporator fan duct.
Inspect the back wall of the freezer compartment and look for screws or round plastic buttons or plugs. If there are round plastic buttons, carefully pry them off the freezer wall with a flat-blade screwdriver.
Remove the screws located on the back wall of the freezer compartment. Pull the back wall off to remove the evaporator cover and expose the evaporator coils and the evaporator fan of the refrigerator.
