International Comfort Products N9MP1100F14C1 Air Pressure Switch
The job of the pressure switch is to determine whether the blower fan is running. This pressure switch is part of the collection of safety devices in place to keep you safe from any injuries. Some pressure switches are constructed with a manual reset, from which the switch will have to be manually reset before you can continue using the system.
Signs that the Pressure Switch is Beginning to Go Bad
- The right temperature indoors seldom fully achieved.
- Bad voltage running through the switch.
- The furnace or AC is unable to run correctly.
