LG LMN090CE Limit Switch
The main reason limit switches are made is because if the air is not warm enough then you will never get hot air through the ducts. The limit switch contains a sensor in the air handler that can determine if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents.
Major signs limit type switch needs to be replaced
- The heating and AC system will not start or run as it should
- The HVAC system starts to runs spotty often
