Carrier 38EYA030 Air Pressure Switch
The main job of the switch is to sense if the blower fan is on and running. This is one of the most crucial aspects of the whole safety system that is intended to keep everyone in the house safe. A good number of pressure switches today can have a manual reset, which means it will have to be manually reset in order for the system to begin normal operations again.
Signals that the Switch is Failing
- Inaccurate electrical voltage reading from the switch.
- The right temperature is rarely fully achieved.
- The furnace won't ignite.
