International Comfort Products N9MP1100J20C2 Air Pressure Switch
The main job of this type of switch is to sense if the blower fan is doing what it is supposed to do. This pressure switch is one of many other mechanisms designed to keep your family safe and sound. Some particular air pressure switches are constructed with a manual reset, by which you must manually reset it or the whole HVAC system will not continue operation.
Red Flags that your Pressure Switch is About to Fail
- The proper indoor temperature is rarely fully achieved.
- Your furnace can't ignite.
- Incorrect voltage range reading from the switch.
