Lennox CB28UH-030 Limit Switch
The limit switch has a sensor in the heat exchanger that decides when the air is warm enough for the blower to be activated. A limit switch was crafted due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
What happens when my main limit switch is in need of replacing?
- The heating and cooling system will not begin the ignition sequence or run like it ought to
- Your system is beginning to become inconsistent on a regular basis
