International Comfort Products H8DNL075F16A1 Air Pressure Switch
The job of an air pressure type switch is to see if the blower fan is circulating the air as it should. Some pressure switches may have a manual reset, which makes you reset it by hand before you can continue using the system. This switch is just one of many mechanisms designed to keep everyone in the house safe.
Symptoms that your System Pressure Switch is Going Bad
- Your system doesn't actually get to the right indoor temp.
- Bad volt range running through the switch.
- HVAC system is unable to function.
