Carrier 50XZ042300 Air Pressure Switch
The primary function of the switch is to determine whether or not the primary blower is running properly. This switch is one of many other device to keep you from harm. Some different switches are constructed with a manual reset, which forces the system to be reset physically before you can continue using the system.
Signs that your Air Pressure Switch is Beginning to Fail
- Furnace refuses operate at all.
- Bad volt running through the switch.
- The right temp is almost never fully attained.
