International Comfort Products GPFM36K100F Air Pressure Switch
The job of the switch is to sense whether the main blower is running. This switch is one of the critical mechanisms designed to stop injuries or explosions. A lot of switches are equipped with a manual reset feature, which means you have to physically reset it in order for the system to begin normal operations again.
Signs that your Pressure Switch will go Bad
- Your furnace is unable to ignite the gas.
- The expected temperature is never fully attained.
- Incorrect electrical voltage running through the pressure switch.
