International Comfort Products PGF048L120F Air Pressure Switch
The actual job of an air pressure type switch is to figure out if the blower is running properly. The majority of pressure switches have a manual reset feature, which forces the system to be reset physically before the entire HVAC system will continue operating again. This is one of many other devices designed to stop injuries or explosions.
Signs that your Switch is in Need of Replacement
- Incorrect volt reading.
- Your furnace will not operate at all.
- The desired indoor temperature is almost never achieved.
