International Comfort Products C9MPD100J14B1 Air Pressure Switch
The main job of the air pressure switch is to sense if the primary blower is blowing air. A good number of pressure switches today are designed with a reset that is manual instead of automatic, which means you have to physically reset it or the entire system will not run. This pressure switch is one of many other safety creations designed to keep everyone in the house safe.
Clues that your HVAC Air Pressure Switch is Beginning to Go Bad
- The furnace or AC can not run.
- Incorrect volt range being read from the pressure switch.
