International Comfort Products NHP260AKA1 Air Pressure Switch
The function of this type of switch is to sense whether the main blower is blowing air. An air pressure switch is just one of many devices that are created to keep everyone in the house safe. Some pressure switches are designed with a reset that is manual instead of automatic, which means it would need to be reset in order for the HVAC system to continue running.
Symptoms that your Switch is Going Bad
- The blower fan refuses to run correctly.
- Incorrect voltage range being read from the pressure switch.
- The set indoor temperature is rarely fully achieved.
