International Comfort Products GNL075N12C1 Air Pressure Switch
The primary function of the pressure switch is to sense if the air blower is running properly. This pressure switch is a very critical piece of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions. A good number of pressure switches today are constructed with a manual reset, which means it will have to be manually reset or else the system will cease to function.
Signs that the Pressure Switch has Gone Bad
- Furnace refuses operate.
- Bad voltage reading from the switch.
- The expected temperature is almost never reached.
