GE AZ75E09EACM1 Air Pressure Switch
The main job of this type of switch is to sense if the primary air circulator is doing what it is supposed to do. Some pressure switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically before the entire HVAC system will continue operating again. An air pressure switch is one of the key aspects of the whole safety system that is intended to stop injuries or explosions.
Symptoms to Look for when the Switch is About to Fail
- The right temperature is rarely achieved.
- Your furnace will not operate.
- Incorrect voltage reading.
