Lennox 13ACD-024 Limit Switch
A normal limit switch has a sensor in the heat exchanger that can determine when the air is warm enough for the air to begin normal home circulation. Limit switches were created because if the air never warms up then you will never get hot air through the ducts.
Indications critical limit switch is not going to last much longer
- System refuses to kick in nor will it stay running longer than 10 minutes
- The system is beginning to act weird occasionally
