Carrier 48XZ060090300 Air Pressure Switch
The main function of the pressure switch is to determine whether the blower is doing what it is supposed to do. Some particular air pressure switches are programmed with a manual reset, which means it will have to be manually reset before the HVAC system will continue. This is one of the vitally important safety hardware devices made to keep you from harm.
Signs that the System Pressure Switch is in Need of Replacement
- The desired temp is hardly ever fully attained.
- The blower fan can not operate properly.
- Incorrect volt being read.
