International Comfort Products PGF048H120F Air Pressure Switch
The function of the switch is to figure out if the primary blower is running properly. This pressure switch is an important part of the safety system in place to keep you safe from harm. The vast majority of pressure switches made today are constructed with a manual reset, which forces the system to be reset physically or the entire system will not run.
Signs that your Air Pressure Switch has Gone Bad
- The correct temperature in the house is rarely achieved.
- Incorrect voltage being read from the pressure switch.
- Your furnace can't run.
