Carrier 58MTB100F10120 Air Pressure Switch
The primary function of the pressure switch is to sense if the blower fan is doing what it is supposed to do. This pressure switch is one of many other safety creations designed to keep everyone in the house safe. Various air pressure switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically in order for the system to begin normal operations again.
Clues that your Air Pressure Switch is About to Fail
- The blower fan can not run.
- The set temperature indoors is almost never fully achieved.
- Inaccurate voltage range reading from the switch.
