LG AMNC123DEA0 Limit Switch
The limit switch contains a sensor in the air handler that determines if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
What are the signs that the limit type switch really needs to be replaced?
- Your LG system is unable to start or continue to run longer that five minutes
- The HVAC system is beginning to initiate and then stops time after time
