Carrier 50ZP036300 Air Pressure Switch
The main job of the pressure switch is to determine whether or not the blower fan is doing what it is supposed to do. This switch is one of the vitally important safety mechanisms designed to keep you from harm. Some particular air pressure switches are constructed with a manual reset, which makes you reset it by hand or the entire system will not run.
Signals that the Switch is Going Bad
- Bad voltage range being used by the switch.
- The blower refuses to function.
- The correct temperature is hardly ever achieved.
