Whirlpool ATE1245BPP0 Air Pressure Switch
The job of the pressure switch is to sense whether the blower is doing what it is supposed to do. Some different switches are programmed with a manual reset, from which it would have to be reset manually in order for the system to begin normal operations again. This pressure switch is just one of the many indispensable facets of the HVAC safety checks that are dedicated to stop injuries or explosions.
Important Signs that the System Pressure Switch has Failed
- System does not actually get to the right indoor temperature.
- Furnace can't ignite the gas.
- Inaccurate volt reading.
