Description
The Carrier 331709-790 Kit is a Carrier air conditioning unit’s thermal expansion valve (TXV) replacement kit. This is a finger-sized component that regulates the flow of refrigerant all through the system; it is a pressure-controlled valve. The low pressure causes the TXV to operate partially wherein a different flow is produced. Such a level of control provides the better cooling and the overall efficiency of the system. Replacing a bad TXV can help you fix the problem of refrigerant flow and cool working of your Carrier air conditioner.
