Whirlpool ATR0943CPP0 Expansion Valve
Every air conditioning system contains an expansion valve that permits the refrigerant to expand back to its low-pressure vapor state from a liquid. An air conditioner would not produce cooled air if the valve was not functioning.
What signals that my AC expansion valve really needs to be replaced?
- The air conditioned flow is much warmer than it ought to be streaming from the vents
- The air conditioner takes too long to cool
