Lennox XP14-060 Air Pressure Switch
The main job of the switch is to sense if the blower fan is doing what it is supposed to do. An air pressure switch is part of a small, but important collection of device to stop injuries or explosions. Some particular air pressure switches are constructed with a manual reset, which means you have to physically reset it before the entire HVAC system will continue operating again.
Signs to Look Out for when the Switch is About to Fail
- Inaccurate electrical voltage reading from the switch.
- Your furnace will not ignite.
- HVAC system does not get to the correct temp according to the settings on the thermostat.
