Carrier FV4BNF003000 Air Pressure Switch
The job of the pressure switch is to determine whether the primary air circulator is circulating the air as it should. Some different switches may have a reset feature that is manual, which means it will have to be manually reset before the HVAC system will continue. This pressure switch is one of the critical safety creations designed to keep you safe.
Signs that the System Pressure Switch is Already Going Bad
- Wrong voltage being read.
- The desired indoor temperature is rarely fully achieved.
- The furnace or AC will not run correctly.
