Payne PG8MAA066135AAJA Air Pressure Switch
The function of the air pressure switch is to sense if the main blower is running. Various air pressure switches are designed with a reset that is manual instead of automatic, which means you have to physically reset it before the entire HVAC system will continue operating again. An air pressure switch is part of a small, but important collection of hardware devices made to keep your family safe and sound.
Signs of a Failing Pressure Switch
- The right temp is rarely achieved.
- Wrong volt range reading from the switch.
- The furnace won't operate at all.
