International Comfort Products C9MPD100J20A1 Air Pressure Switch
The main function of the switch is to figure out if the main blower is running properly. A good number of pressure switches today may have a reset feature that is manual, from which it would have to be reset manually in order for the HVAC system to continue running. This switch is just one of many safety creations designed to stop injuries or explosions.
Clues that your Pressure Switch is Beginning to Go Bad
- Furnace can't ignite.
