Samsung AM27A1C13 Air Pressure Switch
The function of the pressure switch is to sense whether the primary blower is on and running. A good number of pressure switches today are designed with a reset that is manual instead of automatic, which makes you reset it by hand before the HVAC system will continue. This switch is one of many other devices designed to stop injuries or explosions.
Clues that your Air Pressure Switch is Starting to Go
- Bad voltage running through the switch.
- The correct indoor temperature seldom fully achieved.
- The furnace refuses ignite.
