LG AMNH093D4A0 Limit Switch
A normal limit switch has a sensor in the heat exchanger that decides when the heated air is warmed to a point for the main blower to kick in and circulate the air. This is important because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air.
What happens when my critical limit switch is almost going bad?
- The HVAC system will not even start or continue to run longer than a minute
- The system is beginning to become inconsistent often
