Lennox XP19-060 Air Pressure Switch
The actual job of the air pressure switch is to determine whether or not the primary blower is doing what it is supposed to do. An air pressure switch is one of the critical devices designed to keep your family safe and sound. A lot of switches are designed with a reset that is manual instead of automatic, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again.
Red Flags that your Pressure Switch is Beginning to Go
- Incorrect electrical voltage running through the pressure switch.
- The blower can not function.
- HVAC system does not actually get to the right indoor temperature.
