Lennox 14ACX-018 Air Pressure Switch
The function of the switch is to see if the primary blower is on and running. An air pressure switch is one of the critical safety creations designed to keep you safe. Some particular air pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again.
How do you Know when the System Pressure Switch is Starting to Go
- Your furnace will not operate at all.
- The expected temperature indoors is hardly ever fully attained.
- Bad voltage reading from the switch.
