Carrier 48GS Air Pressure Switch
The primary function of the pressure switch is to determine whether or not the primary air circulator is doing what it is supposed to do. This pressure switch is part of a small, but important collection of devices designed to keep your family safe and sound. Various air pressure switches can have a manual reset, which means it will have to be manually reset before you can continue using the system.
Important Signs that the Air Pressure Switch is Starting to Fail
- The set indoor temperature is almost never attained.
- Bad voltage range running through the pressure switch.
- Your heating and cooling system refuses to function properly.
