International Comfort Products NBF050B12A1 Air Pressure Switch
The primary function of this type of switch is to sense whether the air blower is running. Some pressure switches are designed with a reset that is manual instead of automatic, from which it would have to be reset manually before the entire HVAC system will continue operating again. This is one of the key devices designed to keep everyone in the house safe.
Signs that your HVAC Air Pressure Switch is Starting to Fail
- The correct temperature in the house is never achieved.
- Wrong voltage range being read from the pressure switch.
- Furnace can't operate.
