Lennox furnace error code e223

If you’re experiencing a Lennox furnace error code E223, it means that there is an issue with the pressure switch. This switch ensures that the furnace’s combustion chamber is properly vented. When the switch detects an issue with the venting, it will shut down the furnace to prevent any potential hazards.
 
To troubleshoot this issue, you can try resetting the pressure switch by turning off the furnace and turning it back on again after a few minutes. If the error code persists, it’s best to call a professional HVAC technician to diagnose and repair the issue.
 
In the meantime, do not attempt to bypass or tamper with the pressure switch. Doing so can create a dangerous situation and potentially damage the furnace. Always prioritize safety and seek professional help when dealing with furnace issues.
