International Comfort Products NDC7125BKA3 Air Pressure Switch
The function of the pressure switch is to see if the primary blower is running properly. This pressure switch is one of the vitally important safety mechanisms designed to keep your family safe and sound. A good number of pressure switches today can have a manual reset, from which the switch will have to be manually reset before the HVAC system will continue.
What to Look for when the System Pressure Switch is Beginning to Fail
- The correct indoor temperature seldom attained.
- Furnace is unable to run.
- Wrong voltage range running through the pressure switch.
