International Comfort Products NDN5100BFC1 Air Pressure Switch
The reason for the existence of this type of switch is to sense if the air blower is circulating the air as it should. This is just one of many devices that are created to keep you safe. Some different switches have a manual reset feature, which, of course, means that it would have to be reset by hand before the system will continue its normal operation.
Signs that your System Pressure Switch is About to go Bad
- Wrong electrical voltage reading.
- The proper temperature is rarely attained.
- The blower will not run.
