Carrier 48GP024060300 Air Pressure Switch
The reason for the existence of the pressure switch is to sense whether the blower fan is running. Most air pressure switches have a manual reset feature, from which the switch will have to be manually reset or the whole HVAC system will not continue operation. This is one of the critical devices that are created to keep everyone in the house safe.
Signals that the Switch has Failed
- The furnace refuses ignite.
- Wrong electrical voltage being read.
- The proper temperature indoors is rarely fully achieved.
