Lennox 10ACE-024 Limit Switch
A normal limit switch has a sensor in the air handler that can determine when the air is warmed to a point for the main blower to kick in and circulate the air. Limit switches exist because if the warmed air is too cool then you will never get hot air through the ducts.
Indications limit switch is failing
- System will not even start or run well for any significant length if time
- The whole system begins to run erratically on a regular basis
