Danger: Replacing these parts requires working with electrical wiring, be certain to unplug the refrigerator before starting work.

1. Unplug appliance
2. Empty freezer section
3. Remove shelves and Ice storage tray
4. Remove 6 screws from evaporator cover.
Note: Remember where the screws with insulated washers go.
5. Use a hair dryer to melt all ice from coil
Danger: To prevent injury or death from electrocution always ensure that the hairdryer does not get wet while in operation.

Note: Remember to route wiring so that condensation does not gravitate to the electrical connections.
