LG AMNH123APM0 Air Pressure Switch
The function of the switch is to determine whether the air blower is on and running. A lot of switches are issued with a manual reset feature, which means you have to physically reset it or the whole HVAC system will not continue operation. An air pressure switch is just one of many devices that are created to keep you safe.
How is it Known when the HVAC Air Pressure Switch has Gone Bad
