Lennox G24-200 Air Pressure Switch
The primary function of the pressure switch is to determine whether or not the air blower is actually running. Some different switches are equipped with a manual reset feature, which means it would need to be reset before the system will continue its normal operation. This pressure switch is just one of many hardware devices made to keep you from harm.
Signs that your Switch is Needing to be Replaced
- Furnace can't operate at all.
- HVAC system does not achieve the desired temperature.
- Incorrect voltage being used by the switch.
