LG AMNH123APM0 Limit Switch

Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a switch in the heat exchanger that can determine when the heated air is actually warm enough for the main blower to kick in and circulate the air.

Key clues of a worsening limit type switch

The heating and cooling system will not start or run for any length of time
The LG system begins to run erratically time after time
