Lennox furnace error codes

If you own a Lennox furnace, you may encounter error codes from time to time. These codes are designed to help you diagnose and troubleshoot any issues that may arise with your furnace. Some common error codes include E228, E233, and E270.
 
E228 typically indicates a problem with the flame sensor, while E233 may indicate a problem with the pressure switch. E270 is a more general error code that can indicate various issues, including problems with the gas valve or control board.
 
If you see an error code on your Lennox furnace, the first step is to consult the owner’s manual or contact a professional HVAC technician for assistance. It’s important to promptly address any issues with your furnace to ensure it continues operating safely and efficiently.
 
In addition to addressing error codes, regular maintenance and cleaning can help prevent issues with your Lennox furnace. Be sure to replace air filters regularly and schedule annual maintenance with a qualified technician.
