Carrier FV4BNF005000 Air Pressure Switch
The actual job of the air pressure switch is to sense whether the primary blower is blowing air. Some different switches are programmed with a manual reset, from which the switch will have to be manually reset or the whole HVAC system will not continue operation. This is just one of many devices that are created to keep everyone in the house safe.
What Signs are Present when your Air Pressure Switch is Beginning to Go
- The right temperature in the house is hardly ever achieved.
- Your furnace will not ignite the gas.
- Incorrect voltage reading.
