Whirlpool ATE1542CPP0 Expansion Valve
Your HVAC system expansion valve makes it easier for the refrigerant to expand into its regular gas state from a high-pressure liquid form. An air conditioner would be broken if the valve was missing.
Some warnings the AC expansion valve has very little life left
- The air conditioned flow is well below the temp it used to be coming into the home
- The air conditioner takes forever in its bid to keep the temperature down
