Payne PH1ZNA024000AAAA Air Pressure Switch
The main job of the switch is to sense whether the air blower is doing what it is supposed to do. A good number of pressure switches today are constructed with a manual reset, by which you must manually reset it in order for the system to begin normal operations again. This switch is part of a small, but important collection of devices designed to keep you from harm.
Warning Signs that the Air Pressure Switch is Beginning to Go
- The correct temp is almost never fully attained.
- Wrong volt range being read from the pressure switch.
- HVAC system is unable to operate properly.
