International Comfort Products NDN5075BFC1 Air Pressure Switch
The primary function of the switch is to see if the primary blower is blowing air. A good number of pressure switches today are constructed with a manual reset, from which the switch will have to be manually reset or the whole HVAC system will not continue operation. This is one of the key facets of the HVAC safety checks that are dedicated to keep you from harm.
What Signs are Present when the HVAC Air Pressure Switch is Starting to Go Bad
- The blower can not run.
- The proper temp is hardly ever reached.
- Inaccurate volt range running through the pressure switch.
