Friedrich P-12 Air Pressure Switch
The actual job of the pressure switch is to sense if the blower is on and running. This pressure switch is one of the key aspects of the whole safety system that is intended to keep you from harm. Various air pressure switches have a manual reset feature, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again.
Important Signs that the Pressure Switch is Beginning to Go
- Furnace is unable to ignite the gas.
- Bad electrical voltage running through the switch.
- The set temp is hardly ever fully achieved.
