LG ARNU363TNC2 Limit Switch
Limit switches exist because if the warmed air is too cool then the house will never get warm enough. The limit switch has a sensor located in the furnace that makes the determination when the heated air is warmed to a point to activate the main blower.
What are the clues to watch out for to know my limit switch is almost going bad?
- The whole system is starting to run erratically repeatedly
- The HVAC system refuses to start or run as it should
