International Comfort Products H9MPD100J14A1 Air Pressure Switch
The reason for the existence of an air pressure type switch is to sense whether the main blower is doing what it is supposed to do. An air pressure switch is just one of many facets of the HVAC safety checks that are dedicated to keep you safe. Some particular air pressure switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically or else the system will cease to function.
Clues that your Air Pressure Switch will Fail Soon
- Inaccurate voltage reading.
- The right indoor temperature is rarely achieved.
- Your furnace will not operate.
