Whirlpool ATE1252RPP0 Expansion Valve
Expansion valves are used in AC systems and permits the refrigerant to expand back into vaporous form from a high-pressure liquid form. Your main AC unit could not emit cold air if the valve was missing.

- Cold air is warmer than it really should be as it comes from the air conditioning unit
