Carrier 38BYC042 Air Pressure Switch
The actual job of the pressure switch is to sense if the main blower is doing what it is supposed to do. Some pressure switches can have a manual reset, which means you have to physically reset it before you can continue using the system. This switch is one of the critical aspects of the whole safety system that is intended to keep you from harm.
Signs to Look Out for when your Pressure Switch has Failed
- Bad volt range being used by the switch.
- Your heating and cooling system can not operate.
- The expected temperature indoors is almost never achieved.
