International Comfort Products GPFM60S140E Air Pressure Switch
The actual job of the switch is to figure out if the blower fan is on and running. A lot of switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically before the entire HVAC system will continue operating again. This pressure switch is just one of the many indispensable devices designed to stop injuries or explosions.
Signals that the Switch is About to go Bad
- The correct temperature in the house is rarely reached.
- Bad volt running through the pressure switch.
- The furnace or AC refuses to run.
