Lennox G40UH-48B-090 Air Pressure Switch
The reason for the existence of the switch is to sense whether the air blower is actually running. A good number of pressure switches today may have a reset feature that is manual, which means it will have to be manually reset or the whole HVAC system will not continue operation. This switch is part of the collection of safety devices in place to keep you safe from potential hazards in the house.
Signs that the Pressure Switch is Starting to Go Bad
- Wrong voltage range running through the pressure switch.
- HVAC system will not run.
- HVAC system does not reach desired temperature.
