Lennox XC15 Limit Switch
Limit switches exist because if the air is not warm enough then you will never get hot air through the ducts. A normal limit switch has a sensor in the heat exchanger that decides when the air is warm enough to activate the main blower.
Signs main limit switch needs to be replaced
- The heating and cooling system refuses to kick in or will not stay running as it should
- The Lennox system begins to act weird more than once
