Lennox 13ACX-048 Air Pressure Switch
The primary function of the air pressure switch is to see if the blower fan is actually running. An air pressure switch is part of a small, but important collection of devices designed to keep you safe. A lot of switches are issued with a manual reset feature, which means it will have to be manually reset or the whole HVAC system will not continue operation.
Warning Signs that the Switch is Starting to Fail
- The correct indoor temperature is hardly ever attained.
- Wrong voltage being used by the switch.
- Your heating and cooling system will not operate.
