Lennox XP19-024 Air Pressure Switch
The function of an air pressure type switch is to determine whether the blower is blowing air. This pressure switch is one of the vitally important safety devices designed to keep your family safe and sound. A good number of pressure switches today are issued with a manual reset feature, by which you must manually reset it or else the system will cease to function.
How is it Known when the Switch is Starting to Fail
- Bad volt range running through the pressure switch.
- The blower will not function.
- The set temperature indoors is hardly ever achieved.
