Carrier 48XPN048090300 Air Pressure Switch
The job of this type of switch is to determine whether the primary blower is doing what it is supposed to do. The air pressure switch is an important part of the collection of safety devices in place to keep you safe from potential hazards in the house. Some particular air pressure switches may have a manual reset, which makes you reset it by hand or the whole HVAC system will not continue operation.
Signs to Look Out for when the HVAC Air Pressure Switch is Starting to Go Bad
- The proper temperature seldom fully achieved.
- Incorrect voltage being used by the switch.
- The furnace or AC will not operate properly.
