Friedrich VHA09K Air Pressure Switch
The actual job of the pressure switch is to sense whether the main blower is running properly. This pressure switch is one of the key aspects of the whole safety system that is intended to stop injuries or explosions. A lot of switches are programmed with a manual reset, which means it will have to be manually reset before the system will continue its normal operation.
Warning Signs that the System Pressure Switch is About to Fail
- Bad volt being used by the switch.
- The furnace is unable to operate.
- System does not actually get to the right indoor temperature.
