Lennox CBX26UH-018 Limit Switch
The limit switch contains a sensor in the heat exchanger that determines when the air is warm enough for the main blower to kick in and circulate the air. Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
How do you know if your critical limit switch is in need of replacing?
- The heating and cooling system refuses to start or run like it should
- Your system starts to run inconsistently on a regular basis
