First i killed the power and water supply to fridge. Then i removed all the racks in freezer and the 1/4" screws for rack supports with nut driver. Next i removed the evaporator cover 1/4" screws to gain access. Then i removed the the 1/4" screw that holds the evaporator at the bottom and moved the evaporator outward to remove the heater element. Then i installed new heater element from the bottom of the evaporator making sure it was in the center of the evap coils.
Next i replaced the defrost thermostat cutting the old wires. Then stripped and crimpped the new thermostat in place making sure of the same installed postion as removed.
Next i replaced the defrost timer located at the bottom left using philips head screw driver.
Next i replaced the water filter by turning it counterclockwise to remove.
