Whirlpool ATR1552RPP0 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand back into its natural gas form from a high-pressure liquid form. Any air conditioner would most likely give you heated air if the expansion valve was broken.
Signs of a defective Whirlpool expansion valve
- Your AC unit takes a long time in its effort to cool the house down
- The cold airflow is definitely not as cold as you are accustomed to being blown into the house
