International Comfort Products N9MP1050B12C2 Air Pressure Switch
The actual job of this type of switch is to sense whether the main blower is running. An air pressure switch is one of the vitally important safety facets of the HVAC safety checks that are dedicated to keep you from harm. Some particular air pressure switches may have a manual reset, which means you have to physically reset it or else the system will cease to function.
Important Signs that the Pressure Switch is Starting to Go Bad
- The furnace will not run.
- The desired indoor temperature is almost never fully achieved.
- Incorrect volt range running through the pressure switch.
