Carrier 48HJE014 Air Pressure Switch
The main job of the pressure switch is to see if the air blower is on and running. The majority of pressure switches may have a reset feature that is manual, from which the switch will have to be manually reset before you can continue using the system. This pressure switch is part of the collection of safety devices in place to keep you safe from harm.
How to Know when the Switch is Beginning to Fail
