International Comfort Products H8MPN150J20A1 Air Pressure Switch
The actual job of the pressure switch is to sense whether the air blower is actually running. This is one of the key device to keep you safe. Most air pressure switches are equipped with a manual reset feature, which means it will have to be manually reset before the HVAC system will continue.
Signs that the Switch is About to go Bad
- The furnace or AC will not function properly.
- Inaccurate electrical voltage running through the switch.
- The proper temperature indoors is hardly ever achieved.
