International Comfort Products GNE050B12G1 Air Pressure Switch
The actual job of the pressure switch is to see if the main blower is on and running. A lot of switches have a manual reset feature, which means it would need to be reset before the entire HVAC system will continue operating again. This is one of many other aspects of the whole safety system that is intended to stop injuries or explosions.
How do you Know when the HVAC Air Pressure Switch has Failed
- The correct temperature in the house is almost never achieved.
- The furnace refuses run.
