FREEZER ICED UP/REFRIGERATOR WARM

Defrost circuit was inside the control assembly inside the refrigerator so I snapped the two release clamps located to the rear of the assembly (lights and controls). Slid the whole assembly cover off and removed the lightbulbs and two screws right above them. In from of that is the temp switches and directional slider, removed the two screws holding that. With the four screws out, removed whole assembly and laid it dowm on the first shelf, defrost circuit is at the back right, easy change out but take note which way the 4 prong plug fits into the circuit board. Refrigerator was back to normal in about 6 hours.
