Goodman P1256806F Air Pressure Switch
The primary function of the switch is to sense whether the blower fan is on and running. Most air pressure switches are constructed with a manual reset, which means it will have to be manually reset in order for the system to begin normal operations again. This switch is one of the vitally important safety facets of the HVAC safety checks that are dedicated to keep you from harm.
Signals that the Switch will go Bad
