International Comfort Products H8MPL075B12B1 Air Pressure Switch
The job of this type of switch is to determine whether the blower fan is doing what it is supposed to do. The vast majority of pressure switches made today are designed with a reset that is manual instead of automatic, which makes you reset it by hand before the system will continue its normal operation. This switch is an important part of the safety system in place to keep you safe from potential hazards in the house.
