Lennox XP13-048 Air Pressure Switch
The primary function of the air pressure switch is to sense if the primary air circulator is blowing air. This switch is one of many other devices designed to keep everyone in the house safe. Some pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running.
How is it Known when your Pressure Switch is Starting to Fail
- Your heating and cooling system can not function properly.
- Inaccurate voltage running through the switch.
- The correct temperature indoors is almost never attained.
