International Comfort Products T9MPD050F12A1 Air Pressure Switch
The function of this type of switch is to sense whether the blower fan is running. The air pressure switch is part of the collection of safety devices in place to keep you safe and keep your family safe. A good number of pressure switches today can have a manual reset, from which it would have to be reset manually or the entire system will not run.
Signs to Look Out for when the HVAC Air Pressure Switch is Starting to Go Bad
