If you own a Lennox furnace and have encountered an error code E270, it is important to address the issue immediately. This error code indicates a problem with the furnace’s pressure switch, which ensures that the furnace is operating at the correct pressure level.
 
This error code has a few potential causes, including a clogged air filter, a malfunctioning pressure switch, or an issue with the furnace’s venting system.

Ignoring an error code like E270 can lead to further problems, including reduced efficiency, increased energy bills, and even a complete furnace breakdown. To avoid these issues, it is important to address any error codes as soon as they arise and to keep up with regular maintenance of your furnace.
