Lennox 14ACX-048 Air Pressure Switch
The job of an air pressure type switch is to determine whether the air blower is running. Some pressure switches may have a manual reset, which forces the system to be reset physically or the whole HVAC system will not continue operation. This switch is part of a small, but important collection of mechanisms designed to keep you from harm.
Important Signs that the Switch is About to Fail
- The expected indoor temperature is almost never achieved.
- The furnace or AC can not run correctly.
- Bad voltage running through the pressure switch.
