International Comfort Products GPFM24K060F Air Pressure Switch
The primary function of the pressure switch is to determine whether the blower is actually running. This switch is one of the vitally important safety devices designed to keep you from harm. Various air pressure switches may have a manual reset, which means you have to physically reset it in order for the HVAC system to continue running.
Warning Signs that the Switch is Starting to Go
- The desired temperature indoors seldom achieved.
- Furnace won't run.
- Wrong voltage reading.
