Whirlpool ATE0942BPP0 Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand into its normal low-pressure vaporous form from a liquid. An air conditioner would produce no cooled air if the expansion valve was totally worn out.
Signals the AC expansion valve has to be replaced
- The outdoor AC unit takes a really long time to actually cool as it should
- The air conditioned air is much warmer than it really should be exiting the air handler
