Friedrich MW24C3G Air Pressure Switch
The reason for the existence of the pressure switch is to determine whether or not the blower fan is running properly. This switch is one of the key aspects of the whole safety system that is intended to keep you from harm. The majority of pressure switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand before you can continue using the system.
What to Look for when your Pressure Switch has Failed
- The proper temperature in the house seldom achieved.
- Bad voltage range being used by the switch.
- The furnace won't operate at all.
