International Comfort Products HHP224GKA1 Air Pressure Switch
The main function of this type of switch is to see if the air blower is doing what it is supposed to do. This switch is one of many other devices designed to keep you from harm. The majority of pressure switches have a manual reset feature, which, of course, means that it would have to be reset by hand or the entire system will not run.
Evidence of a Failed Air Pressure Switch
- HVAC system can not run correctly.
- Wrong voltage range being read from the pressure switch.
- HVAC system does not actually get to the right indoor temperature.
