International Comfort Products NHP048AKA1 Air Pressure Switch
The function of this type of switch is to determine whether or not the primary air circulator is actually running. Most air pressure switches are programmed with a manual reset, which means it will have to be manually reset before the entire HVAC system will continue operating again. This pressure switch is one of the vitally important safety mechanisms designed to keep you safe.
Signs that the Switch is About to Fail
- HVAC system can not function properly.
- Inaccurate volt reading from the switch.
- The proper temp is rarely fully achieved.
