Payne PY2PNB060115AA Air Pressure Switch
The main job of an air pressure type switch is to sense if the blower fan is running. This pressure switch is one of many other aspects of the whole safety system that is intended to keep you safe. The vast majority of pressure switches made today can have a manual reset, which means you have to physically reset it or the whole HVAC system will not continue operation.
Signals that the Switch is Beginning to Go Bad
- Bad volt being used by the switch.
- The furnace will not operate at all.
- The desired temperature in the house is rarely fully achieved.
