SPT WA-8070E Air Pressure Switch
The actual job of the switch is to see if the primary blower is blowing air. A lot of switches may have a manual reset, which, of course, means that it would have to be reset by hand in order for the system to begin normal operations again. This is one of many other safety creations designed to keep you safe.
Signs to Look Out for when your Air Pressure Switch has Failed
- System does not achieve the desired indoor temperature.
- Your furnace can not operate.
- Bad voltage running through the pressure switch.
