International Comfort Products GPFM18K040F Air Pressure Switch
The main function of the switch is to sense whether the blower is blowing air. This is just one of many devices that are created to keep you from harm. Some particular air pressure switches may have a reset feature that is manual, by which you must manually reset it before the system will continue its normal operation.
Signs to Look for when your Air Pressure Switch is Beginning to Go
- The blower will not operate.
- The desired temperature indoors is hardly ever reached.
- Wrong voltage reading from the switch.
