LG LP070CED Limit Switch
A normal limit switch is a switch in the heating area that determines when the heated air is warm enough to activate the main blower. Limit switches exist because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Subtle cues to watch for in a bad limit switch
- The system starts to runs spotty on a regular basis
- The heating and AC system will not begin or continue to run even though max temp has not been reached
