Carrier 50GL024300 Air Pressure Switch
The reason for the existence of this type of switch is to see if the blower fan is blowing air. This is one of the vitally important safety device to stop injuries or explosions. Some particular air pressure switches are constructed with a manual reset, which forces the system to be reset physically or the entire system will not run.
Symptoms to Look for when the System Pressure Switch is About to go Bad
- The furnace won't run.
- The proper temperature in the house is hardly ever achieved.
- Wrong volt running through the pressure switch.
